Antler brand luggage was made by J. B. Brooks and Co in Birmingham.
1920 The son of J. B. Brooks introduced luggage to his father's company, with leather covered wardrobe trunks for ocean liners, and, as the automobile grew in popularity, with 'motor trunks' which were strapped to the back of a car. He was keenly interested in wildlife, hence the stag's head and the brand name Antler.
