1967 Topps Hank Aaron All-Star
In 1966 Hank Aaron and the rest of the Braves moved from Milwaukee to Atlanta. Aaron saw a drop in his batting average but led the league in homers and RBIs. In the All Star game he was 0 for 4 with a strikeout.
1967 Topps Willie Mays All-Star
Willie Mays' numbers went down in 1966 following his MVP season in 1965. But 1966 was hardly an "off year" for the Say Hey Kid. He was #3 in MVP voting and won his 10th consecutive Gold Glove. In the 1966 All Star game Mays scored the tying run for the NL in the 4th inning.
1967 Topps Bob Clemente All-Star
I'm not sure why Topps insisted on calling Roberto Clemente "Bob". He was Roberto on his rookie card in 1955 and again in 1956. Suddenly in 1957 he became Bob. He was called Roberto on cards made by Post, Fleer and even Milton Bradley in the 60's. Topps would finally call him Roberto again on his 1970 card but referred to him as Bob on the Batting Leaders card from that same year. In the 1966 All Star game Clemente had a single and a double in 4 at bats.
