There were many great sets in the 1960's, and for me, the '65 set is my favorite barely edging out the 1963 set.
That being said, what is your favorite card(s) from the '65 set?
Mine is Tony Oliva. I love the colors of the card and I am a HUGE fan of the big All-Star Rookie Trophy's on cards, whether they are stars or commons.
