Cubist french pewter art deco tea set

A very interesting cubist art deco french tea set.
Circa 1930.
4 pieces + tray that is not original to the set but also 1930's modernist and silver plated.
(This is normal because large pewter tray does not exist. Metal is not adapted. Only small pewter tea set comes with pewter trays).
Excellent condition.
Signed ERMES on the pots.
Stamped underneath "ETAIN FIN GARANTI DEPOSE"

Higher pot is 20cm high 7.9in.
Tray diameter is 33.5cm 13.2in
