It's a tidy promotion for both the Brewers and local businesses, who together will "Put Milwaukee in First Place."
For each man, a matching ad; "Get Your 'Phil" at Kalt's Restaurants" for second baseman Phil Lewis, "Spring Suits That will Catch Your Eye" for backstop Johnny Hughes. I particularly like equating Cross Safety Razor's "Close Shave" with pitcher "Doc" Watson. There are some real groaners, though, including pairing catcher Jimmy Block with the slogan "Don't Let Anything Block You From Coming Here for Your New Spring Suit", and especially the ad in the center, featuring player/manager Harry "Pep" Clark and slogan "You Can't Retire Harry Clark—and You Won't Have to Re-Tire Your Auto—If You Equip Your Tires with American Tire Protectors".
There's another ad I find equally interesting, this time for its connection with the Brews.
Dewey's Sporting Goods proudly proclaims that they made the Brewers' uniforms. The one example of a jersey we have from that season bears in its collar the tag of a P. Goldsmith and Sons of Cincinnati, Ohio. Perhaps that jersey was sold to the Brews by Dewey's, or was a re-purposed jersey from an earlier season.
As for Dewey's itself, it was founded by Charles J. Dewey, who also sold jewelry. An ad for his sporting goods store appears in our 1903 tavern scorecard under the name "Victor Base Ball Goods".
This photograph shows Dewey's Sporting Goods as it appeared in the 1940s, still run by the Dewey family and still on Water Street:
I don't know how long Dewey's could make the claim that they supplied the Brewers; by the early 1930s Burghardt Athletic Goods had taken over that business.
