In 1917 CFKeller exhibited his painting, “The Sheep-fold”  in the notorious New York First Annual Exhibition of The Society of Independent Artists. The exhibition was formed on the model of the Parisian Salon des Independants, showing works by any artist for a fee of $1 and membership of $5. It was the largest show ever assembled in the USA. Duchamp was on the board and suggested works be hung alphabetically. Duchamp also submitted his work “Fountain” by the non-existent R Mutt which was notoriously not admitted and Duchamp resigned from the board.
