I just picked this one up:
fcgamer is my username on other forums. I can verify that if necessary.
Up for offer is the Ultravision Condor Attack game.
There is some label damage to the cart, otherwise it is in nice condition. It is untested though, since I don't have access to an Atari 2600, but due to its condition, I believe it to be in working condition.
Any questions, please ask. Thanks!
