Cramer Sportcards produced full-color sets for other teams earlier in the 1970s, so Phoenix likely used this 2-color design to save money. They did offer an additional premium (the team picture), but made young collectors mail away 5 card tabs and 75 cents for it.
Check out this History of Phoenix Minor League Baseball 1958-1980, which mixes player profiles, year-to-year stadium pricing, and local history into an epic of "Page Down" proportions.
Larry Prewitt shows up near the bottom of that history page and his balloon-like 9+ ERA and 2+ WHIP reflected the Giants' own tough 1980 season. How bad did things get?
"At the end of the miserable season, the Giants were short of players so they activated first baseman Gerry Jestadt...official scorer for home games and a radio color commentator. In addition, a Phoenix television sports director, Bill Denney, started the final game of the year. Denney, who was 48 years old, had pitched as a pro from 1950-58, but never higher than AA."No wonder minor league scorekeeping can be a nightmare to sort out. The guy in charge of official records might be on the field himself!
