Most of these posters are a common size as I am fairly sure they are reproductions. Go to a Michaels or similar lady-shop and look at the frames and mats you can buy off the shelf. It is not hard and is certainly cheaper. I have spent a kings ransom on one of mine because it is original and mint. Archival glass and muslin backing etc. Not needed for a twenty dollar poster. Besides, think of the manufacturing process required to make a poster versus the tooling needed to roll-form aluminum frame channels or the NC cutters needed to shape a pre-made wooden frame. Think of it like a woman, sure she's pretty cool but holy **** she looks good all dolled up. J
