I love this card.
My mom is from outside of Cincinnati, and (with her leadership) by the time I became old enough to care about sports, the Reds were my favorite. It didn't hurt that they were really good -- not the same powerhouse that they'd been in 1975-76, but still good. The Reds were back in the playoffs in '79 before age caught up with their best players.
For a simple head shot, isn't there a lot to like about this Foster card? The sideburns and the eyebrows, the hat and the bat, the V-neck stripes. Then there's the card style. I just love that script Topps (and O-Pee-Chee) used for team names that year, and I also love that All-Star badge. This set isn't particularly renowned for its design or photography, but it's my favorite anyway. I collected these cards when I was six; maybe the first set you collect should be your favorite.
Foster hit a massive 52 home runs in 1978, with 149 runs batted in. He led the National League in RBIs three years in a row -- 1977-79 -- the only player since Joe Medwick in the late '30s to do so. (The last player to lead the American League in RBIs three straight seasons is Cecil Fielder, 1990-92. Good trivia.)
