Teak buffet Gaston fish 1960s

This 3-door sideboard is a rare creation from the 1960s by French designer Gaston Poisson. Made of teak, it bears the master's signature: the original brass keys featuring the GP logo. The design combines clean modernist lines with high-quality craftsmanship. Behind the three doors lies a well-thought-out storage space with shelves and wooden compartments integrated into the inside of the doors. The sideboard is in good condition, with slight wear on the top surface, consistent with its age. It was purchased by my parents in the 60s and is part of a dining room set with a table and 4 chairs (in my possession). Aside from the original keys that authenticate the designer and a plaque indicating the number, I have not found any other proof of authenticity for the piece.
