Vintage articulated pine screen by Jomain Baumann for Melun, France 1920-1930

According to the brand's metal plate, this is probably one of the first models manufactured in the 1920s-30s. We couldn't find a reference to a model larger than this. Its 3 meters wide, fully unfolded, allow it to stand and stand straight, making ripples, occupying a width of about 250 cm. Very good general condition with light traces of use. Slight separation of about 20 cm of two leaves in the upper left part (see photos). See the detailed photos as they are part of the item description. Any defects to be reported are indicated therein.
