With all your resources and connections I've seen you and others say you can and have completed runs of GA series within a fairly short time frame (less than 5 years), and obviously 1930s books are hard to find in any condition sometimes, and then you have these Centaurs which had distribution problems to make them even tougher. Something I've wondered though, have you ever come across one of these super tough books in the wild, which you were able to scoop up ridiculously cheap? Or are you always surrounded by other collectors/dealers that price books like these to you accordingly?
