KLC, that's a great rare find. Pilots were there for only one season. It was very much an 11th hour deal for Bud Selig to get the team to Milwaukee for the 1970 season:
After a winter and spring full of court action, the Pilots reported for
spring training under new manager
Dave Bristol, unsure of where they would play. The owners had given tentative approval to the Milwaukee group, but the state of Washington got an injunction on March 16 to stop the deal. PNSI immediately filed for bankruptcy — a move intended to
forestall post-sale legal action.
[30] At the bankruptcy hearing a week later, Milkes testified there was not enough money to pay the coaches, players, and office staff. Had Milkes been more than 10 days late in paying the players, they would have all become free agents and left Seattle without a team for the
1970 season.
[31] With this in mind,
Federal Bankruptcy Referee Sidney Volinn declared the Pilots bankrupt on April 1—six days before Opening Day—clearing the way for them to move to Milwaukee. The team's equipment had been sitting in
Provo, Utah, with the drivers awaiting word on whether to drive toward Seattle or Milwaukee.
[32] The move came so late that Selig had to scrap his initial plans to change the team's colors to navy and red in honor of the
minor-league Brewers of his youth. Instead, the Brewers were stuck using old Pilots' uniforms, with the team name replaced.
One legacy of the Brewers' roots in Seattle is that their colors are still blue and gold, although the shades have been darker since 2000.
