I got this 1977 Topps Carl Yastrzemski in my very first pack of cards. Something about the picture and robust stats on the back made it my favorite right away. Even though I was in a family and town full of Twins fans, I became a Red Sox fan and was hooked on card collecting because of this card. I now have two or three others of this same card in much better condition, but this will always be my favorite.
Interestingly, I can identify the cards from that first pack because my mom wrote my name on them. After that, and for the next two years, I wrote my first initial "E" on them myself.
