Hi there

I got the double ender cartridge robin hood / Sir lancelot boxed for the colecovision system. The games work on my colecovision, no problem but i have a question for the box.
It is written "plays on atari vcs 2600" but in the front of the box, there's a sticker "for coleco".
Is this box a really coleco box or did i buy the coleco game with a 2600's box?
