Rush proofs

I have a number of MGM rush proofs in my collection, remarkable (ironically?) for the beauty of their finish. A number of them are connected to Marion Davies' silent version of QUALITY STREET (1927), which co-starred Conrad Nagel, Helen Jerome Eddy, and Flora Finch - one of the first comedy film stars, and best remembered for her partnership with John Bunny. The film's cinematography is credited to Hendrik Sartov.
