Hello Collectors -
I just started building a low-grade 53 Topps set and I have found that the text color for the player bio on back switches between white and black. Can anyone help me answer some questions

- Does anyone know where to find the most accurate list of which cards(I don't think it is all) have been printed with both?
- If any of you have completed a set, did you chase both white and black or just get one of either?
- If anyone has low grades they are looking to unload, I'm buying. I still need all the big names except Campanella, Spahn.

Thanks for the help.
Barry
