This catalogue represents the eighth major Russia sale David Feldman SA has had in the last five years. Again, we bring to the market an unusually large presentation of Russian material. This auction’s offer follows the amazing success of the five Dr. Casey’s Russian Post Offices in the Chinese Empire sales, which were offered between April 2012 and December 2016. The current auction presents to the market a wonderful offering of Soviet Union. It represents most certainly one of the most comprehensive collections of the Soviet period we have ever offered, with a particular emphasis on blocks of four, plus some important imperforates, errors and airmails. In addition we also have a fine selection of some early Imperial Russia with no less than two unused 1857 10k, plus some lots from the Casey Ship mail collection, a fine array of Zemstvos in large blocks and complete sheets, and a group of general Russia collections.
