August 30, 2013 – Sean Kelly announces From Memory: Draw a Map of the United States , a project conceived and produced by Hisachika Takahashi. From 1971 through 1972, Takahashi, a Japanese artist living in New York, asked twenty-two fellow artists to each draw or paint a map of the United States entirely from memory on the handmade Japanese paper he provided. This exhibition presents, for the first time in New York, those twenty-two works and Takahashi’s own drawing, in addition to material from Takahashi’s archives, providing a unique glimpse into the New York art world during this period.
