Until they closed their doors just recently, Remington had been the oldest American gunmaker, in continuous operation since it was founded by E. Remington in Ilion, New York in 1816. About a century later, in 1912, Remington merged with Union Metallic Cartridge Company, a massive ammunition manufacturer, to form a new powerhouse, Remington-UMC. This Vintage 1920s Remington UMC “POPULAR KLEANBORE CARTRIDGES” Dog Bone Bullet Board Advertising Poster is in Fair Condition, with a 1 1/2” x 3/4” “V” shaped piece missing from the middle top edge, a similarly colored piece having been placed behind it as a repair after the fact, some surface tearing along the tops of the letters in “KLEANBORE” at the upper middle front, a 3/4” x 5/8” “V” shaped tear in the middle right edge, some wrinkling at the lower right matting, some scattered fading and wrinkling to the front of the poster, and with some overall age wear evident. Otherwise, the poster is in fine shape, with no other damage to the fragile paper construction. Most interestingly, it measures 16 5/8” x 11 3/4” in 19 3/4” x 16” gold cardboard matting, remains well protected with a tight fitting plastic wrap securing it to a poster board backing (this is a perfect temporary means of protection until it’s framed by the next owner if they so desire), and bears the classic “REMINGTON / KLEANBORE / REMINGTON” red ball “dog bone” logo at the upper middle front, with “POPULAR” and “CARTRIDGES” above and below, respectively, and a determined outdoorsman and a wild bear at the upper right and left front corner, respectively. It exhibits a wide variety of Remington-UMC rimfire cartridges, revolver and pistol cartridges, and sporting rifle cartridges printed in fine detail around the front, carries “See Opposite Side for Ballistics and other Information” along the lower middle front, and dates to the early 1920s. A fine example of a very rare, original Vintage 1920s Remington UMC “POPULAR KLEANBORE CARTRIDGES” Dog Bone Bullet Board Advertising Poster.
