I am currently in my 60's and retired, but when I was a young boy, I collected cards showing the various EMD and GMDL diesel locomotives designed by General Motors for their customer's locomotives that they built. Are there any other collectors out their that have some of these? Most of these contain a lithograph painting of the railroad's design on the locomotive they purchased from GM. These were used on calendars, and sometimes they ended up as large drawings, etc., and most were drawn by artist Ben Dedek. I have a large group of these and would like to contact others that have similar interests. Dick Schneider rjs1936@cox.net
