looks like a movie thing from a theatre. I used to manage one and while most movies had standard cardboard signs like this one.
Others had more elaborate things. That Wall-E was probably part of a bigger display like this.
The complicated ones are a pain in the ass to get together and the cardboard is razor sharp. But they're designed such that you can't wear gloves or you'll never make any of the connections. Cool when finished though!
lol it was weird seeing this getting attention now, but yea the person who lives in that duplex owns that wall-e, havent seen it outside since then....I shouldve stole it when I had the chance...
