The issuance of the Eldev-Otchir symbol stamps in August 1924 marked a monumental moment in Mongolian postal history. These were the first stamps issued by the newly established Mongolian People’s Republic, symbolizing the country’s shift towards independence and modernization. With intricate designs and fascinating varieties, this issue has become a treasure trove for philatelists.

The Design and Symbolism
The stamp design features the Eldev-Otchir symbol, an emblem of national unity and identity. Designed by L. Schonauer and printed at the Lithographic State Printing Works in Moscow, the stamps were inscribed in black and offered in a range of denominations. The values increased in size as the denomination rose, with dimensions varying from 19×25 mm (1 cent) to 30×39 mm ($1).
