Card fact: There are three players in this photo (although you can see only the cap of one of them). That ties the Rick Monday card for the most players in one photo, so far. Excluding photos with players in the distance. And team cards, of course.
What I thought about this card then: No knowledge of it.
What I think of this card now: What a strange card. Dave Duncan, who looks vaguely like Jay of "Jay and Silent Bob" fame, appears lost in thought. The rest of the photo is dominated by that giant hand in the left corner.
Other stuff: Duncan was your typical good-field, no-hit catcher from the 1960s and 70s. He was much valued behind the plate as a fielder and handler of pitchers. Of course, he used that ability to become one of the most famed pitching coaches of recent history, Tony La Russa's right-hand man for all eternity, apparently.
Duncan has two sons, Chris and Shelley, who have had middling success in the majors. I recently saw Shelley Duncan in an Indians uniform. I had no idea he was with the team. After success with the Cardinals, injuries have plagued Chris, who is now in the Nationals organization.
