I love it. It instantly reminds one of the movie, and without the poster, it'd be very subtle. Most of my replicas are displayed in a more "natural" setting. Who wouldn't want to try on that hat when they come over?
I'm also always surprised / impressed by how much non-scifi props really capture the general public's imagination. My Goonies key and coin get way more compliments than any of my other stuff.
Oh, and my grandmother actually has a very similar carpet bag, and we used to tease her. I believe it was made out of upholstery, not carpet. . .
