The 1948 Swell Bubble Gum Sport Thrills baseball set is comprised of 20 cards, each measuring approximately 2-7/16” by 3”. Produced by the Philadelphia Gum Company, the set honors the National Pastime’s most thrilling moments up to the post-war world. The cards have a black-and-white image framed with a baseball-themed border, the title “Sports Thrills Highlights in the World of Sport” at the top of the card, and the title of the card along the bottom. The backs give the story of the event pictured on the front. Most also promote Bob Feller’s then-recently printed “How to Pitch” book. The set is anchored by Dramatic Debut: Jackie Robinson ROY (#3), Most Dramatic Homer: Babe Ruth Points (#12), Great Slugging: Lou Gehrig’s Four Homers (#14), and Three Run Homer in Ninth: Ted Williams’ Homer (#16). Card #s 9, 11, 16, and 20 are more difficult to obtain than the other cards in this set, although the entire set is a challenge to secure in high grades due to their unusual sizes, resulting in many being found with folds or wrinkles along the edges.
