M16 Helmet with Blue Max Trench Art

A German M16 WW1 helmet with original Blue Max trench art. Helmet shell is missing its liner. Artwork on the mid-grey painted shell features a large Pour Le Merite Blue Max cross to the front on a front-to-back Iron Cross ribbon pattern. A 1916 date is painted on the back of the shell along with illegible Gothic script, and the central core from a Prussian belt buckle is screwed into the crown. Metal is thin on the crown, with some small holes. Maker and size stamped ET66. A unique piece of WW1 history.
