I recently had a chance to add a couple stamps to my Ernie and Billy collections. These are inserts from the 1961 Topps set. There were 208 different stamps in the set and came two to a pack.
Half of the stamps, like Ernie's, were green. He was on two different two panel stamps, sharing one with Chico Fernandez and another with Pedro Ramos.
Billy's stamp is the other color, brown. It's interesting to me that he was included in the set, since 1961 was his first full year in the majors. Topps must have seen him as an up and coming player; for once they were right!
As you can see from the pictures, both stamps are in really nice condition, considering that they are 50 years old. In fact, the Williams stamp becomes the oldest piece in the PC. They both came at very reasonable prices, and are nice additions.
