Here is a rejection letter sent to Andy Warhol from the Museum of Modern Art, New York dated October 18, 1956.
Dear Mr. Warhol:
Last week our committee on the Museum Collections held its first meeting of the fall season and had a chance to study your drawing entitled "Shoe" which you generously offered as a gift to the Museum. I regret that I must report to you that the Committee decided, after careful consideration, that they ought not to accept it for our Collection. Let me explain that because of our severely limited gallery and storage space we must turn down many gifts offered, since we feel it is not fair to accept a gift of a work which may be shown only infrequently. Nevertheless, the Committee has asked me to pass on to you their thanks for your generous expression of interest in our Collection.
Alfred H. Barr, Jr.
Director of the Museum Collection
P.S. The drawing may be picked up from the museum at your convenience.
