Intriguing cubist sculpture

An intriguing cubist head shaped sculpture made of die cut tin advertising plate for "Agfa". (circa 1930).
Wood structure.
Unsigned. Definitely inspired by the best cubist sculptors.
Tin litho plate is 1930's.
Wood structure is old. Hard to tell if 1930 but shows wear on edges.

This sculpture is NOT advertising display, but a unique artist work.
(Cubist artists often used daily items to build their works. Like Picasso in "Table in a café", with a Pernod Fils bottle or like newspaper covers in many paintings by George Brake or Juan Gris)
No more info ! Just stunning and old and unique conversation piece !
