This one is all about the combination of form and graphics and language for me--a proud quick loader, ready to squeeze and release! Made by the American Can Co. for dusting powder used for cleaning rifles I believe, with great lettering and what looks like an eye at the center of the label, which marks the spot to press it. Late 19th century.
4 1/2" l x 2 3/4" in diameter x 1 1/8". Good condition, sound and sturdy, with general wear and scattered light rust.
