Boston Red Sox jersey 1901-1907
The Red Sox were one of the founding members of the American League and started playing in 1901. However, they weren’t initially called the Red Sox; they started out as the Boston Americans (to differentiate themselves as the AL team in Boston, which they shared with the National League’s Braves). During those years they had two uniforms. The home ones were white, the roads were grey, and both had BOSTON across the chest in blue letters.
Both uniforms were worn with high blue socks while the caps were white with horizontal blue stripes. The only change during these years was in 1902 when BOSTON was replaced with the letters BA (one letter on either side of the chest) rendered in Old English lettering (think of the Detroit Tigers D for an idea of the font). During this period, all of the jerseys were pullovers with collars and lace-up necks.
