I've got 11,835 Cubs cards from 84 different brands listed on a spreadsheet. A random number generator picked five cards, one each from the past several decades.
1950s / 1960s: 1958 Topps #209 Bob Anderson The righty pitched in only 8 games for the Cubs in 1957, but that was enough for Topps to include him in the 1958 set, and in an early series, too. Anderson spent the first four months of the season at AA Fort Worth. He was recalled to the Cubs in early August and split his time between the bullpen and the starting rotation. He posted a 3-3 record for the Cubs. The highlight of the season for him was a complete game win over the Phillies on August 27, his first big league win.
1970s: 1973 Topps #552 J.C. Martin Martin is on the list of players who played for both the Cubs and the Sox. He was with the Sox at the start of his career, from 1959-1967. By the time he got to the Cubs in 1970, he was a broken-down back-up catcher. The Cubs got him just before the season, and when Randy Hundley went down with a season ending knee injury, he became one of several catchers who tried to fill Hundley's position. By 1972, Martin saw limited action, appearing in only 25 games. He was released by the Cubs at the end of spring training in 1973. He spent about half the season in AAA, but hung them up for good after playing in only 53 games.
1980s: 1983 Fleer #493 Bill Campbell Fleer gives us a shot of Campbell at the Vet in Philadelphia. Soup led the National League with 81 appearances. He logged 122 innings of work, which come to an average of an inning and a half per outing. Most relievers don't do that any more.
1990s: 1993 Fleer # 25 Ryne Sandberg The 1993 season was an up and down one for Ryno. He broke his hand in spring training and didn't return to the Cubs lineup until early May. In mid-September he dislocated a finger and missed the rest of the season. In between, he hit .309 in 117 games. I'm guessing the broken hand affected his power as he had only 9 homers. He also had a career first in 1993--on May 26 he was ejected by first base umpire Charlie Williams.
2000s: 2013 Topps 1972 Mini #12 Anthony Rizzo The RNG grabbed a card from this season, which hasn't happened very often. Rizzo's numbers this year were disappointing, as his average has really taken a beating. Hopefully he'll figure things out for next year. Otherwise we may have Adam Dunn II on our hands.
