I know almost nothing about soccer cards, particularly vintage ones, but I saw this Chix Bubble Gum Football Picture album for sale on eBay and decided to pick it up; the price was right for the hobby library. Inside is a complete 1956-57 Chix Confectionary Famous Footballers Set.
After some research, the set appears to be considered a second series of Chix Famous Footballers following one dated to 1955.
There are quite a few variations to the cards in this set and the album as well; I found this one with a different cover and red text on the inside.
If you know anything else about this set or the albums, please leave a comment.
