Al, they are really hard to find. I have a connection in Argentina who sends me card offers from time to time. He knows I like Pele cards but even so has only been able to offer me two of the 1965s. They will set you back at least $200 even in crappy condition [most were pasted into albums by the kiddies].
Re the Heinerle, I like the action image. That is an interesting set. Lots of great athletes in it and even the rookie card of Meadowlark Lemon of the Harlem Globetrotters.
