Well a Quad poster from Pulp fiction was a free give away if you bought the VHS tape 'as it was in those days'. I don't think they would of given away that many Originals, So they must have been repro's. And the $64,000 question, Yes it was 40"x30". and came rolled. I belive some other stores give away sets of stills. So there was a choice. Ohh, and I'm sure the poster was single sided.
I think your safe with Shawshank.
