The last one I seen sell went for over $100 bucks. I picked this one up for a fraction of that
the last one i saw the guy couldnt sell for $25! relisted it a couple of times [same design you have, the yellow]
all depends on timing i guess? its sort of at the funny age were people have moved onto newer things. but hasnt yet quite blossomed into the cult classic it is destined to be!
to be honest i dont think the posters are really that great design wise. but i love the movie!!!! best thing ive seen in a while
