I Never saw the blue old mill in person. I do recall a T-206 reprint set made in the sixties, (maybe early 70's) that did not say reprint on them. They were good. In that set there were some odd colors used for the backs, and I think old mill was printed in green and/or blue. The fronts were real good. Brown toned names and cities. Correct dots (printing matrix) etc. These reprint sets were scarce at the time and I havent seen any in 30 years, I have no idea who produced them, some, I'm sure, have made it into authentic collections. jes sayin.

ps any other old timers remember those sets?
