These are armors for man and horse made of etched steel created by German armorer, Wolfgang Grosschedel (1517-1562). I took this photo at the Arms and Armor Room of the Metropolitan Museum of Art last Sunday. Dated 1535, the man's armor is stamped with Grosschedel's personal mark. The etched decoration includes human figures and ornaments copied from engravings by the German printmaker Barthel Beham (1502-1540).
Incidentally, a model was arrested the other day, just seconds after she stripped naked in this same Arms and Armor Room for Zach Hyman, a professional photographer who specializes in nude photoshoots in public places.
