This 501-card set was produced by the Baltimore Orioles in conjunction with Crown Gasoline Stations and Coca-Cola. The cards measure approximately 2 1/2" by 3 1/8" and feature every Oriole player in the team's modern history (1954-1991). The cards were issued in four series, with ten twelve-card sheets per set. The first set was given away at the Orioles May 17th game against the California Angels, and the following day the set went on sale at Baltimore area Crown gasoline stations for 1.99 with an eight gallon fill-up. The second set was given away at the Orioles June 28th game against the Boston Red Sox, and again it went on sale the following day at Crown gasoline stations. The third set was given away at the Orioles August 11th game against the Chicago White Sox and went on sale on the same day. The fourth set went on sale at Crown gasoline stations on September 16. The cards are arranged alphabetically by player and checklisted below accordingly.
