It's the art for one of the HG Toys jigsaw puzzles from 1979. There were 4 different jigsaws produced.
To my understanding, Veronica Cartwright read lines for Ripley during her audition. I'm guessing at some stage, there was a change of plan to cast her in that role and no one told HG Toys or the art had been finalised for the jigsaw and was too late to change. I believe Cartwright didn't find out she had the character swap to Lambert until she turned up on set for her first day of shooting. I don't know if that's accurate or not. Wouldn't surprise me if it was.
