What I couldn't explain then was why the trophy hadn't been engraved since 1951, how the Packers wound up with it when the Rams were the last champions to be listed on it and why the trophy wasn't shaped the same as the one pictured in the Green Bay Press-Gazette on May 1, 1962, the day after Rozelle gave it to Lombardi.

Part of the problem was that the Press-Gazette couldn't find the original photo in its files and the engraving was illegible in the newspaper copy.

Thanks in large part to Jack Giambrone, a Packers fan in Dayton, Ohio, and collector of Lombardi-era memorabilia, much of the mystery can now be untangled.

Shortly after my column appeared, Giambrone sent Packers curator Brent Hensel a copy of the original Press-Gazette photo and Hensel, in turn, showed it to me.

Giambrone's photo showed enough of the engraving to suggest the Thorp in the Hall of Fame might be at least part of the trophy given to Lombardi by Rozelle.

Next, I called Katie Foust, archival assistant at the Green Bay Packers Hall of Fame, Inc., which owned the trophy, to see if she had ever seen anything that looked like a loose piece to a trophy.

Sure enough, Foust had the base of a trophy on her workbench and was planning to polish the plating, not knowing what it was, but figuring it was of some value.

During Hall of Fame, Inc.'s move from its previous office, she had discovered the base at the bottom of a cardboard box tucked away in a closet.

"It was like an epiphany," Foust said of my call. "I knew something was missing, but I didn't know it went to a much more significant piece of history."

By then, the Thorp traveling trophy was in three parts. The main part, which listed the champions through 1951, was on display in the Hall of Fame. The base, which listed the champions for the next 16 years, was located in another building blocks away. There also was a separate figurine of a ball-carrier broken off by the leg.

Hensel took the separate pieces to Rummele's Jewelers of Green Bay, had the parts reattached and prominently placed the trophy in our "100 Seasons" exhibit in the Hall of Fame.

That's where it is showcased today.

In the meantime, we've also learned the Cleveland Browns were given the trophy after winning the 1964 NFL title. On Jan. 16, 1965, the Cleveland Plain Dealer ran a picture of two women who were employees of the Browns holding the Thorp Trophy. The caption noted, "the trophy arrived at the Browns' offices at the Stadium yesterday." It also stated the Chicago Bears had been in possession of it previously.

But that fairly recent discovery by Tony Dick, former director of the Browns Alumni Relations, also raises other questions.

How and when did the Packers relinquish the Thorp after winning it again in 1962? And then how did they get it back after they beat Cleveland in the 1965 NFL championship for their third title under Lombardi?

So far, I've been unable to uncover anything about another Thorp Trophy presentation involving Lombardi or the Packers after the one at the Elks Club in the spring of 1962.

Did the Browns bring it to Green Bay for the '65 championship game and leave it with the Packers? Was there an unpublicized presentation at the NFL meeting held in Miami Beach, Fla., less than a week later? Is it conceivable the trophy could have been shipped from the Packers to the Bears to the Browns and back to Packers?

Here's something maybe even more puzzling?

Why are the 1960 Eagles, the only NFL champion from 1934 through 1967, not engraved on the trophy, especially when there was a space saved for them that's still blank?

I've since found a UPI Telephoto of former NFL commissioner Bert Bell presenting the trophy to Colts owner Carroll Rosenbloom at an NFL meeting in January 1959, less than a month after the Colts won the first of back-to-back titles.

Did the Eagles gain possession of it thereafter and just not bother to engrave it or did the trophy simply pass from Rosenbloom to Rozelle to Lombardi in the spring of '62?

The 1968 Colts and '69 Vikings aren't inscribed on it either, although there might be a logical explanation for that. There was no room left to list them.

A few of the companies that engraved the trophy over the years placed stickers at the bottom of the base and the most recent was put there by Green Bay Trophy Co., which suggests it was the last to engrave it. But that was really the only lead those stickers provided.

John Keegan, who took over Green Bay Trophy from his father in 1973 and owned the business until 2014, recently examined the Thorp trophy and offered some interesting insight, but couldn't answer with certainty any of the previous questions. His late father, Don, bought the business in 1963.

John said the trophy was probably custom cast when it was made in 1934 and would have been expensive then and still worth a good chunk of money today because of the silver.

He said it appeared the team names, from 1934 through 1959, were cut into the metal with a pantograph machine, or any number of them. In turn, he said the names from 1961 to 1967, including the Packers five times, were almost certainly engraved by hand, a rare and lost art.

While John said neither his father nor the previous owner did hand engraving, either one could have easily sent the plates to a colleague in Chicago to do the job.

In fact, Keegan surmised that the same person or business engraved the last seven champions and his former company was likely the one.

"They look like they could have been done at the same time," he said, "but there's no way of knowing that."

While this latest search into the Thorp's history solved the bigger mystery, it gave birth to another.

The NFL's original plan in 1934 was to give each champion a smaller replica along with the traveling trophy. A second trophy was awarded through 1939 and all six original replicas can be accounted for today.

That was determined by Sarah Quick, the Packers' assistant director of communications, through a survey she took prior to my first column on the Thorp. Recently, she took a second survey of the other three teams that won replicas – the Giants with two, Detroit and Washington – and learned Thorp is correctly spelled on those four trophies.

The Packers have two replicas: One for their 1936 championship, which is in storage at the Hall of Fame, Inc., warehouse, and another for their 1939 championship, which is on display on the second floor of the Hall of Fame.

On both, Thorp was misspelled "Thorpe."

The NFL minutes from the February 1937 meeting where the traveling Thorp was presented to the Packers for winning the 1936 title suggests they were given money to buy their own replica and that might explain the mistake. There's a good chance the replicas were engraved locally and Ed Thorp was anything but a household name in Green Bay. But that's trifling stuff.

The biggest mystery has been solved.

The now 84-year old Ed Thorp Memorial Trophy was dismantled and misplaced, maybe more than once, but never lost and for more than 50 years has been where it belongs – in the possession of the franchise that won it the most times.
