From the blog of James Gurney:
Most art schools once had large plaster cast collections, but many destroyed them in the wanton orgy of iconoclasm of the 1950s, 60s and 70s. The cast collection belonging to Vassar College in New York State (seen intact above) was a typical sad story. The director of the Art program, Agnes Clafin, ordered the destruction of the collection in the 1940s arguing that casts were no longer useful in teaching, and that “this was a time to innovate, to bring Vassar up to speed.” Only a few casts at Vassar escaped annihilation.
