Found - upcycled retail fixtures

I see these all the time in junk stores - I think that they are store fixtures(for announcing sales and prices etc on a retail display) But when they are grouped like this, as picture frames, they are really special, aren't they? They look like they're from Pottery Barn! Makes me want to go to the thrift store to see if I can find some right now! These are from a grouping by Bricolage Life on this Flickr group. It's a wonderful grouping and great photography.
