I would almost consider erasing (if it's pencil, looks like it might be) the Stargell and Walker autos to have a larger, cleaner Clemente. Both of those guys are easy autos, even after their deaths.
I had something similar, a mid 60s Senators program, that was signed oddly (weird angles, upside down, etc) by a bunch of the team. Most of the players were ho-hum, but Gil Hodges was on there, so I just cut him off the program. I never regretted cutting it up, because the whole piece together wasn't anything more than a nice Hodges signature anyway.
I am not a big fan of random autos on items with text (program covers, ads, etc). Now if they signed their picture in a yearbook or something like that, then it's a different story. Very nice piece though. Clemente is a gem of an auto to have.
