You from the Pacfic NW, Yakima Red is a local brew from our neck of the woods. I'm sure not the expert in beer memoriblia, but I would say most printed mirrors are silk screened by various print shops around the nation. Much like lots of the work I do, just prints. Breweries will contract these items out for distro to various bars. So to find the manufacture, History, and cir. would be very difficult. As for value, your best place to establish this would be local pubs, Ask your friend the bartender what they would be willing to pay. I would guess you would be looking at 20 to 40 bucks a piece, but that would just be a guess. Ebay would be very hard, based on size shipping cost and general fragility of the items. Again I am in no way a expert, just wandered if you were here in the N.W. and the rest just followed

P.S. Welcome to the forum and thanks for posting
