Peaky Blinders Management protection service Shelby Brothers Ltd Mobster t-Shirt. The Peaky Blinders’ dominance came about from beating rivals, such as the "Sloggers", whom they fought for territory in Birmingham and its surrounding districts. They held control for nearly 20 years until 1910, when a larger gang, the Birmingham Boys led by Billy Kimber, overtook them. However, even though they had disappeared by the 1920s, the name of the "Peaky Blinders" became synonymous slang for any street gang in Birmingham. Soft ring-spun cotton tee.
