The road uniforms were similar to somejerseys (Dressed to the Nines) that the Senators wore over the year with WASHINGTON in block letters on the front. On the back, the name was in blue with the number in red, a look the Chicago Cubs have used (sportslogos.net).
The Americans logo, shown here is was on the sleeve.
