Tim NewcombIt's exactly what this board should be for.
I happen to have a full set of 1911 Obak, so I counted them up and got 41 cards with this leaflike design on the backs. The number may be slightly higher as 3-4 of mine have serious back damage and I can't be positive about them.
This includes all the names you mentioned, which suggests that it's not a back variation that exists on some copies and not others, but a back type that exists on all copies of some subjects.
I'll type out a complete list of the subjects that have the design when I have a little time.
In the meantime, does anyone else have info to add about this fun discovery?
