3600-N Small Stars Vending with Toy

This is the most unusual find on ebay.  These are definitely Sticca cuts.  The seller didn't know if the toys and stickers were packaged together.  I think they were packaged together for a vending machine or carnival favors, etc. . . I have not seen these toys packages like this before or since.
