After redesigning the Leaf set as a premium brand in 1990, Donruss added another set to its stable in 1991 with the first release of Studio. The 264-card set is a significantly different set than the other sets on the market, the set is all black and white portraits with only trivia and biographical information on the card back. The set is made up of ten players from each team (only nine players and one coach for the Angels), three managers, and a header card that was not numbered.
