Semaphore Gallery was a contemporary art gallery founded by Barry Blinderman and A. James Shapiro in 1980 in New York City, located at 462 West Broadway in the SoHo, Manhattan district. In 1984, Semaphore East was also established on the corner of 10th and Avenue B in the East Village, Manhattan district.[1] Semaphore East closed in 1986, and Semaphore Soho moved to 136 Greene Street, across from Leo Castelli. The gallery closed in the summer of 1987, when Blinderman accepted the position of Director at University Galleries of Illinois State University.[2]
