The Mego "Batman Command Console",1977, price paid: $10
It's basically a big 'ole walkie-talkie. It's supposed to work with other consoles and walkie-talkies, taking incoming and making outgoing calls and Morse code messages. I'm sure it was a flawless system; perfect for the Dark Knight's weekend telemarketing job.
King Tut and Egghead have stolen priceless Faberge Eggs from the Egyptian Antiquities Wing of the Gotham Museum.
TO THE BAT-POLES, OLD CHUM!
PS Also found these cool Superman Movie collectibles; a movie treasury book and a 12 print art portfolio, $5 for the pair. Sweet.
