So evidently there are two different 1963 Topps 2nd Series Checklists as well:
Was one of them printed on the 1st Series sheet?
Now of course I need to add two more Checklists, a yellow topped 2nd Series and a red topped 6th Series, to my 1963 Topps Baseball card collection. Are many/any of you other 1963 Topps Baseball card collectors content with just one of the Checklists for each series?
