When the Pilots moved to Milwaukee in 1970, a set of promotional trading cards were distributed throughout the state of Wisconsin. The slogan on the back read, "Milk for lots of protein, it's the Flavor-est." Supposedly, Flavor-est was the name of the dairy that distributed them. I can't confirm that, but labeled this the "Flavor-est Gallery" anyway. Although I shy away from Brewers memorabilia, I thought this set would be of interest, because this is the nucleus of the team that would have left 1970 spring training for Seattle.
Thanks to Steve Bowles for his help in assembling this section!

As you can see in this card, the 1970 Brewers uniforms retained the piping on the sleeves and the same lettering style as on the Pilots' road jerseys.
