More than just a cool prop, the TPS-L2 is part of history. That particular Walkman was the first portable personal cassette player ever released, according to Sony. It retailed for a whopping $200 (about $589 in today's dollars).

The TPS-L2 went on sale July 1, 1979, in Japan and then in June the following year in the U.S., according to walkman-archive.com.

Finding the Walkman is the easy part — locating the classic orange MDR-3L2 headphones is the trick. For the moment, there isn't a single solo orange pair listed on Ebay. Still, there are plenty of complete sets up for auction.

The classic gadget, which plays a big role in the recently released Guardians of the Galaxy Vol. 2, was first marketed under the name "Soundabout," according to walkman-archive.com. The "Walkman" name followed not long after.

Sony didn't have an answer when Heat Vision asked whether there has been an uptick in requests to once again produce the TPS-L2.

Guardians Vol. 2 enjoyed a massive opening weekend, raking in $145 million at the U.S. box office — 54 percent ahead of the first Guardians.
