I recently traded for 5 cards from this colorful set with my friend Stein. A&BC - also known as the American & British Company Limited - produced sets from 1958 to 1975. They were then purchased by Topps. Topps continued the soccer sets up to 1981.
You can see that the two makers already worked together by the similarity of designs from the Topps baseball and the A&BC soccer cards.
Of course the "with Planet tabs" are more desirable, the ones without were designed to be put in the album. As you can see by the dotted line they expected the collectors to trim off the tab to fit in the album.
I am looking for any trades on these cards. Speak up and get yourself a deal ...
