J Gauthier et Fils........goes back to the 1950s making sticks in France at least. Had a cool logo with the tricolor French Rooster and in the "white" section a stylized tennis racquet was in its place.
Then in the 70s had a new logo with an agressive G with an Arrow coming from it and again a small French Tri-Color flag in the G.
As a typical French company put out lots of what could be called exotic frames, putout some models like the Colombe, Overcome Pro Graphite and had auto frames for Henri Cochet and Yvon Petra.
Stayed around till the early 90s - had granite sticks that show up today on various auction sites (mainly in France, Belgium, Germany, Switzerland......).
Always saw them in the larger French sports stores like Intersport, Sport 2000, Decathalon....etc)
