These aren't cartophilic by any stretch of the imagination. Little booklets, sold in the 1960's but Americans can't get enough of them. The pages featuring golfers, boxers and baseball are quickly removed from each volume, placed in card holders, graded and sold for big bucks across the pond. The rest of the pages are just discarded. I thought I'd include information here. There are two booklets featuring sports stars - Giants of Sport (No. 6) and Giants of Sport II (No. 22) Thanks to Steve F. for photos of the covers and jeromebelasco for a scan of the index of Giants of Sport II.
UPDATE (30-05-2019 11:26):  All the missing names have been added to the checklist for the first booklet thanks to an anonymous comment.
