Help indentifying

My friend sent me this bag has tag from 86 with Columbia pictures but I cant find this anywhere. Any clue what it might be or any info at all

It looks like it could be a miniature school bag, or maybe something that would be fixed to a bicycle… While a lot of merchandise was produced for The Real Ghostbusters, we unfortunately don’t have an exhaustive list detailing everything that was made. :frowning:

Yeah I cannot find a thing. The closest was thermos lunchbox with the same graphic but this seems so random
