A Charlie Brown Christmas, the 50-year-old animated special that taught generations of Peanuts fans the true meaning of Christmas and how to make any Christmas tree look special is now being immortalized in U.S. Postal Service Stamps.

The colorful, and instantly classic, stamp collection commemorates the special’s 50th anniversary and the 65th anniversary of the Peanuts comic strip (which is on Oct. 2). Each stamp will feature an iconic image from the show, including Charlie Brown bringing home the world’s saddest and most famous Christmas tree, Pig Pen’s dirty snowman and Snoopy’s over-decorated dog house. There are also non-denominational "forever" stamps, which means that they can be used to mail First Class letters no matter what the postal rate.

“It will be a great joy to see these iconic images when I open my mailbox this holiday season,” said Peanuts creator Charles Schulz’s widow, Jean Schulz.

A Charlie Brown Christmas was the Peanuts' first animated special. Airing on Dec. 9, 1965, it introduced us to Vince Guaraldi’s jazz music and the Peanuts characters’ unusual dance styles. It was also an unexpected hit and led to numerous specials and feature films. The Peanuts return to the big screen this November in their first CGI animated film.

Among those attending the stamps dedication ceremony at the Charles M. Schulz Museum in Santa Rosa, California on Thursday will be Jean Schulz, Charles Schulz’s son, Craig, and A Charlie Brown Christmas Executive Producer Lee Mendelson. The stamps go on pre-order Wednesday and should arrive well before the holiday card sending season.
