Painted Sallet
From the Royal Armouries:
The Sallet is dated from 1490 and is of German origin. It is incredibly rare for painted decoration to survive on helmets such as the Sallet, and the color perhaps challenges traditional views of the medieval period as being full of dark colors and little decoration. The top of the helmet bears a flame design, while the lower part has a chequered pattern in red, white and green. Painting was a cheap way to decorate armor in this period, however, only a few examples of painted armor are still in existence.
