Collection of material sent to New Yorker architecture critic Lewis Mumford, including three typed manuscripts signed by Wright, two ALSs from his wife Olgivanna, four Taliesin Square-Paper mailers, a hand-colored invitation for Frank and Olgivanna’s wedding, two unsigned telegrams from Wright, and some additional ephemera. The typed manuscripts include: a six-page article entitled ‘Wright and Europe’ by Giancarlo de Carlo, signed and inscribed at the top in blue ballpoint, “Lewis—This had to be said by Europe—no body home to tell the truth—? Frank”; a nine-page article by Wright entitled ‘In the Cause of Architecture: The International Style,’ signed and inscribed at the top in blue ballpoint, “To Lewis—F.LL.W”; and an eleven-page typescript entitled ‘Taliesin Square Paper 16,’ signed and inscribed at the top in blue ballpoint, “To Lewis, F.LL.W.” An additional assortment of four 4 x 6 pages of messy pencil sketches is of special interest, as a cover sheet annotated in Mumford’s hand describes them as sketches by Wright from 1952. Another item included is an envelope addressed to Mumford, notated in Mumford’s hand, “F.L.W. in wartime?, spectacle for posterity, LM, 19 Jan 45.” In overall fine condition. Wright and Mumford had a well-known embattled relationship—sometimes friends, sometimes enemies—embodied in this interesting collection of American architectural history.
