Offered in this lot is a Kirt L Hart Remington Guns & Rifles Advertisement Envelope, Tucson, Arizona Territory, circa 1901. Provenance: Tombstone Western Heritage Museum, Tombstone, Arizona. S. L. Hart (Samuel Lombard Hart) was a very highly regarded and skilled gunsmith over his ten years in Tombstone plying his trade to the cowboys, gamblers, lawmen, and gunfighters of Tombstone. Some of Hart's more notable clients were US Marshal Wyatt Earp, Doc Holiday, outlaw Ike Clanton and Buckskin Frank Leslie. Hart most likely taught his sons the gunsmith trade so that after Hart moved the family to Tucson in 1890, Hart's son, Kirt L. Hart, continued in the family business opening his own gun shop, K. L. Hart Store. Eventually the business expanded into K. L. Hart Sporting Goods and later Smith Sporting Goods Company. Kirt had a similar stamped hallmark as his famous father, which was the letters S and L over a "heart," an artistic yet compact and simple way of saying "S.L. Hart."; "K. L. Hart" over a "heart,". The envelope is a Remington Guns and Rifles multicolour advertising cover with an image of a female hunter with her rifle at left of front, "Copyright F. E. Getty 1901" printed behind her legs.
