An amazing throwback over a century old, this pair of baseball sunglasses was invented by Hall of Famer Fred Clarke in 1912. Unlike the modern-era flip-style, these glasses were actually bolted into the brim of the hat, and are of all-metal construction except for the lenses. This sample, which is missing a lens, sources from the family of Pirates teammate Max Carey, and is a photomatch to Clarke's trademark glasses. “Lloyd” is stamped into the metal bracket. Clarke was the player-manager for four of Pittsburgh’s pennants, and actually held the patent for the sunglasses of the type offered here. Straight from an ESPN article: "A big breakthrough came in 1912, when Pittsburgh manager Fred Clarke devised a cap with snap-down lenses bolted right into the brim. This design was used for a while, but true sunglasses didn't catch on until Foster Grants hit the market in 1929 and polarized lenses became available in 1936."
