Constructed from tan cardboard with black printed blue paper labels, the lid and sides bear the circled "US" logo, with the lid label marked "50 Cal. .44 HENRY FLAT/RIM FIRE/ METALLIC CARTRIDGES/For Model 1866 Henry and Winchester Rifles/and Colt's Rim Fire Revolvers/MADE IN U.S.A./THE UNITED STATES CARTRIDGE COMPANY,/NEW YORK, N.Y.,U.S.A.", and the seal marked for "BLACK POWDER" and the Lowell, Massachusetts address.

Fine overall, with some foxing and wear on the labels and some stains and scuffs on the box. The seal has been broken. A faded ink stamp is present on the underside, possibly "124-3".
