Oh come on, dozens? There aren't any at conventions, and I have been to quite a few recently. Maybe one on Ebay last year. I think it's the toughest TAT issue.
Let me pass on this story to yah' all. I use to set up at some of the NY Creation Cons back in the early 1980's. It was either one of the Koch brothers or G. Dolgoff that came up to me with a short stack of TAT number ones. I bought two copies at $25 apiece. Since I was not a Baker collector back then, I traded or sold them off at some point. They were all in nice VF conditions.
