Russia, P.O. in China, **/*/used. Extensive mint collection written up on album pages with many 100s of stamps and much high values to research. Also seen large multiples with different settings, especially the diagonal overprints in the Cyrillic alphabet. This is more than a work in progress collection and represents a formative study, including reference, of these much underrated issues which have a huge future potential philatelically. An opportunity not to be missed for dealer or collector of this area of Imperial Russia. Please see scans at www.philea.se. (Image1)
