Rare Winchester 50-110 Express Ammo Green Label Black Powder Full Box

This is a full box, 20 original rounds, of .50-110-300 Winchester Express black powder ammunition manufactured by Winchester introduced in the late 1880's.  The two piece, square corner box has the seldom seen green and black label.  In very good plus to near excellent condition the two piece box is solid with a slight edge indent on the top left side with slight seam separation on the top corners.  The label shows slight rub wear with near excellent graphics having a very nice cartridge cut.  The cartridges are in excellent condition, with the correct express bullets with the “X” marked copper inserts and head stamps that read “WRA Co 50-110 EX”.  Among the most collectible of the Winchester calibers and boxes this one is in great condition with the less frequently seen green label.
