Update - JD McCarthy Postcards
Just a quick update. It appears that JD McCarthy postdards were produced in signed and unsigned versions. It is difficult to tell if the autographs were ink or printed on the postcards as part of the manufacturing process.
I just received the cards posted above. It is easier to tell in person if the autographs are real or not. The easiets way to tell is by the half-toning or pixellation of the autograph. Different shades are reproduced with different size white or black dots in the printing process. If the autograph has half tones then the autograph was printed and is not genuine.
This was very difficult to tell just by pictures without closeups, but significantly easier to tell with originals in hand. Sadly, the only "genuine" autograph appears to be from Dick Donovan of the White Sox - circa 1958-ish.
