The first one was done by my father, he did the covers of the programs from 1961-1964. He also did some of the signage at the Rockpile. Within the weekly programs, he did some Bills related stuff like cartoon bodies of the players in the Bill Cody gear with their headshots on the cartoon body. I used to get copies of all of the programs since Dad also was the salesman for Holling Press which printed the weekly programs. Around 1976, Mom in a cleaning frenzy tossed out "those old programs of yours"
The second one is from the AAFC Buffalo Bills from 1947-1949. According to Dad, when the Buffalo Bills came back into existence in 1959, his boss asked him to try to get the Bills account, Mr. Wilson was planning on bringing back the old Bill Cody after one of the west coast teams (LA Chargers) used a version of it in their weekly program. They asked him to do one, and after Mr Wilson gave the approval, he would create a new one about a week or two before the game. I remember watching him draw them first in pencil, then ink, then with the 3 color transparent drapes that would be used for production.
