Estonia. Collection mostly used 1918–41 in album. Absolutely outstanding collection (almost complete) including descriptions of every issue, varieties of different kinds, wonderful covers, etc. Also including two almost complete series "Postgebiet Ob. Ost" cancelled with the specific city cancel "Dorpat" used only during a short period of 1918. Both series expertized (Roots 2020). Please see all scans on our website. Excellent quality. (>300)
