I have an original Malcolm Emmons Type 1 photo of Koufax that I could make available (Emmons stamp on back). Emmons is perhaps the most respected of the Post-war Photographers... His work was used for infinite Sports Illustrated Covers, as well as the famous 2' X 3' SI Posters of the 1960s.
It's a great image of Koufax on the mound. Feel free to email me at
imstroft@yahoo.com I can attach the images in a return email, if you're interested.
Hope this is helpful,
Mark
