I like the above 1975 Topps. It is hard to see his signature on it, but it's there.
Robinson (b. 1948) played in the majors from 1972 to 1977 for the Phillies, Braves and Giants. He had 157 hits, no home runs and a .219 batting average.
I mailed to Robinson on September 28 and got the cards back on October 10, for a 12-day TAT.
