Not sure on this poster but it’s mounted on a gray background. The actual poster is about 14 inches tall and about 10.5 inches wide. The gray backing is posterboard and the Linsey graphic is glued on and I don’t think you’re getting it off there – little stick pads on the corners. The poster part is in pretty good condition – a couple nicks here and there but minimal. Cool graphic and pretty good color on it – it’s not in perfect shape but given 12 years old, it’s pretty good and the pictures show it well. Pretty cool and unique piece that I haven’t seen any others of actually. If you’re a Lindsey Stirling fan or a Lollapalooza fan or both, this might be for you to commemorate 2013.
