I was wondering if any other Kellogg's cards featured players who wore #56. After reading the following story about top players at each number (bleacherreport) I was worried that not many guys wore that number.
The Sporting News also did a list and said no one else was worthy of even being compared to Buehrle as the best player to wear #56.
A Sporcle quiz had twenty players who wore that number. None appeared on Kellogg's cards.
Baseball-Reference.com came to the rescue. I searched for who wore #56 from 1970 - 1983, so I could have missed some guys who wore the number during other years.
1983 - Bert Campaneris (Yankees). He normally wore #19 in his career but Dave Righetti had that number when Bert arrived in New York.
1970 - Don Gullett (Reds). He normally wore #35 in his career.
That's it. I went further to check out all of those who wore #56 in baseball history.
I did find that Gus Polidor wore #56 in 1985 for the Rangers. He was featured in an early post about the Venezuelan Kellogg's card set.
One eight White Sox players have worn #56 and only Buehrle did so for more than three years.
