This 1910 postcard by Walter Wellman indicates no maker. Perhaps this prolific cartoonist self-published? He reserved his copyright on the front, a pretty rare thing.
I don’t know which is weirder about this card — that a fisherman is wearing a tuxedo and spats, or that this dapper fellow would gladly see a pretty girl drowning in order to cop a feel of her ankle. Actually, wait, I do know which is the weirdest — that someone would purchase this card over all the other options they undoubtedly had on offer at the postcard rack.
