The cards in this 726-card set measure 2 1/2" by 3 1/2". Topps continued with the same number of cards as in 1978. As in previous years, this set was released in many different formats, among them are 12-card wax packs and 39-card rack packs which cost 59 cents upon release. Those rack packs came 24 packs to a box and three boxes to a case. Various series spotlight League Leaders (1-8), "Season and Career Record Holders" (411-418), "Record Breakers" (201-206), and one "Prospects" card for each team (701-726). Team cards feature a checklist on back of that team's players in the set and a small picture of the manager on the front of the card. There are 66 cards that were double printed and these are noted in the checklist by the abbreviation DP. Bump Wills (369) was initially depicted in a Ranger uniform but with a Blue Jays affiliation; later printings correctly labeled him with Texas. The set price includes either Wills card. The key Rookie Cards in this set are Pedro Guerrero, Carney Lansford, Ozzie Smith, Bob Welch and Willie Wilson. Cards numbered 23 or lower, which feature Phillies or Yankees and do not follow the numbering checklisted below, are not necessarily error cards. They are undoubtedly Burger King cards, separate sets for each team with their own pricing and mass distribution.
