Hi Jeff-
Interesting project & glad you are having fun with it !! I just checked it out, and had a question. I noticed on the T206 Lajoie & T206 Jennings that it says "unknown back". Does PSA require that you put that term on the registry because that's how they have it listed in their database from the # on the flip, or, can you put in the actual cig. brand on your own?
Just wondering about that. I know it isn't an unkown back to you
Thanks, and congrats on your project !!
Sincerely, Clayton
