They issued 142 before the 2004 and 54 more will be added. Adam Greenberg, he of "the one pitch to the head and on to the DL" fame for the Cubs last year, gets one.
There is also a puckish card, "Half a Minyan: 1946 New York Giants," which pictures the five Jews who played for the team that season: outfielders Morrie Arnovich, Sid Gordon and Goody Rosen; pitcher Harry Feldman, and infielder Mike Schemer. Incidentally, Schemer an example of one of the few times a rabbi's son made the big leagues.
Perhaps the 1946 Giants need a whole minyan as they finished in last place at 61-93.
