Everyone and their brother has one of those Patagonia trucker caps. Here is a unique cap made from an actual rainbow trout. My daughter caught a beautiful Tennessee Rainbow. We made a gyotaku of it. From that original we scanned and digitized an image which has been locally embroidered onto this trucker cap.
Currently there are less than 20 of these caps in existence. It's a Yupoong brand cap-one of the best on the business.
