It is a long shot, but does anyone have, or have images of, any of the specific Dietsche postcards shown in the RPPC below. My theory is a collector took this photograph of the set, including the early Cobb Fielding, in 1907. I'd like to find one of these hand labeled postcards to confirm that theory.
