This set, produced by Sport Star Publishing Company in 1975 as a collectors' issue (though not actually issued until 1976), was withdrawn from the market because of legal entanglements. Because SSPC agreed never to reprint the issue, some collectors feel it has an air of legitimacy. The complete set contains 630 full-color cards, each 2-1/2" x 3-1/2" in size. The cards look similar to the 1953 Bowmans, with only the player picture (no identification) on the fronts. Card backs are in a vertical format, with personal stats, brief biographies, uniform and card numbers printed in a variety of colors. Sets originally sold for $9.99. - 2006 Standard Catalog of Baseball Cards, 15th Edition.
