Hey Adam, have you catalogued the Seidman program cards? They were a limited edition (Appears to be anywhere from 70+ to 200+ per sheet), that I believe were freebies inserted in programs to fans who purchased ringside tickets to specific fights that Seidman printed the programs for.
Cardstock sheets that appear to be designed for trimming on the front, while the backs usually served as bout cards for the fight night the sheet was issued for. Issued in the early to mid 90's. I had almost all of them at one point, but never thought to digitally archive them properly. I want to say there was somewhere between 15-20 different sheets produced.
