2.675x3.25". This set was issued one per box on the backs of various Royal Dessert products over a period of three years. The basic set contains 24 players, however a number of variations create the much higher total for the set. In 1950, Royal issued cards with two different tints - black and white with red, or blue and white with red. Over the next two years, various sentences of the cards' biographies were updated; up to three times in some cases. Some players from the set left the majors after 1950 and others were apparently never updated, but the 23 biography updates that do exist, added to the original 24 cards issued in 1950, give the set a total of 48 cards. Cards are blank-backed with personal and playing biographies alongside the card front photos. Some sample cards can be found with advertising for the desserts on back; they are valued at about double regular card prices.

Warren Edward Spahn was an American professional baseball pitcher who played 21 seasons in Major League Baseball (MLB). A left-handed pitcher, Spahn played in 1942 and then from 1946 until 1965, most notably for the Boston Braves, who became the Milwaukee Braves after the team moved west before the 1953 season. His baseball career was interrupted by his military service in the United States Army during World War II. A few of his many career accomplishments include being a 17 time All-Star, a Cy Young Award and World Series Championship in 1957, led the NL in strikeouts four times and threw two career no-hitters. Warren Spahn was inducted into the National Baseball Hall Of Fame in 1973.
