The tour posters have become somewhat of a cottage industry - limited to something like 600 per show, unique to each show (even back-to-back nights at the same venue have different posters) and sell at the merch tables for $60unsigned/$300signed. Demand is so high for them that you can at least triple those prices selling them on Ebay when you get home from the show. Lots of chatter on fan forums about the ethics of poster flipping etc. Limit is supposedly 2 per person but people have been seen with armfuls, presumably from enlisting friends to help them. Also lots of complaints about the merch lines turning into shitshows with people cutting in, staff not knowing/honoring limits, etc.

Some of the posters on the last leg came with a second clear layer with geometric patterns on then that look pretty damn cool when framed with a gap between the pieces.

I bought copies of the Philly and AC posters on Ebay a week or so after the shows for about $25 each, and ended up getting a refund from the seller because the quality was so shit. The AC one had a white blob on it that made it very obvious the seller had grabbed a picture of someone's poster - including glare from a light or flash - from the internet and blown it up to poster size.
