On 10 July, the Elva postal administration overprinted the stock of USSR stamps that it had at its disposal. In addition, stamps brought to the post office by citizens were also overprinted. The horizontal overprint of the inscription βEesti Postβ in two lines was applied by a hand rubber stamp in black ink.
The issue was not caused by postal needs and was mainly intended to pursue political objectives. The overprint stamp was composed of individual letters, which led to the emergence of various differences due to contamination, wear, cleaning, and reassembly. The stamps are known with cancellations from localities situated near Elva (Puka, Tartu, etc.).
They remained in circulation until 12 August 1941.
