HELP sourcing the origin/photographer(s) of some late 1960's images
 

I have a group of color film "postives" - like a negative except in full color. They are medium format (2 3/8" X 3 1/8")

They are clearly professionally composed images. I found a number of them (or images clearly from the same photo shoot) that were used by TV Sports Mailbag, Inc/Photofie Elmsford, NY on "Hall of Fame induction cards" - narrowed that companies use of them between 1989 and 1992 (possibly longer - I didn't check every image). I also found a number of them used by Pacific cards during a similar time span. I am trying to determine the photographer(s) and origin of them. Mike Cramer would have owned Pacific cards at the time - if anyone has contact information for him, that might be helpful.

Any other assistance is appreciated.
