Two different proof sheets for the elusive Black Sun Rubaiyat.  No complete copy of this book was seen by Black Sun bibliographer George Minkoff.  The only known complete copy is Caresse Crosby's own copy, which was presented as an addition to the Queen's Doll House, London, sometime after 1930.  A set of proof sheets is at Southern Illinois University.
