Any list that excludes exhibit cards and postcards and premiums is deeply flawed, IMO. Just off the top of my head on your list:
Exhibits:
Tiger Flowers: 1923
Al Brown: 1925
Tommy Loughran: 1925
Kid Chocolate: 1928
Conn, Graziano, Wlliams, Ortiz, Saddler, Jack and Gavilan's exhibit cards all predate the sets listed.
Pascualito Perez: 1948 card from his gym and 1965 Argentinean card and a number of discs from Argentina pre-1967.
Carmen Basilio: Exhibit card, various premiums
Carlos Monzon: 1971 supers
Kid Gavilan: 1951 Bread For Energy
Jimmy Bivins: 1940s Exhibit card
Maxie Rosenbloom: 1928 Exhibit
Fidel LaBarba: 1926 Exhibit card
