1988 Rangers Mother's

This set consists of 28 full-color, rounded-corner cards each measuring 2 1/2" by 3 1/2". Starter sets (only 20 cards but also including a certificate for eight more cards) were given out at the ballpark and collectors were encouraged to trade to fill in the rest of their set. Cards were originally given out on August 7th. Photos were taken by Barry Colla. The sets were reportedly given out free to the first 25,000 paid admissions at the game.
