I ran across this non baseball Real Photo Post Card that bears Carl Horner's embossed studio logo on the front of the RPPC. It has a blank CYKO postcard back. I have seen plenty of Horner photos, cabinets and even postcards with his photos issued by others such as Rotograph, but never a RPPC actually issued by him. Is it possible he ever issued baseball RPPCs directly? Unlikely, but a tantalizing thought indeed!
