Le Corbusier, France.

Original Le Corbusier poster circa 1968 from an early exhibition poster  at the “Le Corbusier Foundation”, featuring a distinctive graphic design. 
The poster promotes the Le Corbusier Foundation, dedicated to the work of the renowned Swiss-French architect, urban planner, designer, and painter, Le Corbusier (Charles-Édouard Jeanneret-Gris).
The poster features a striking graphic with a large, stylized shell-like or organic form in black and green against a background of red, yellow, and green stripes, typical of mid-20th-century modern art and design.
The Le Corbusier Foundation works to preserve and promote the architect's legacy, including his architectural designs, paintings, and writings, which were instrumental in the development of the International Style.
