Slovakia · 1939 · Various (Heller and Koruna)

This complete set of 22 stamps features various definitive issues of Czechoslovakia from 1920-1938, overprinted with a diagonal bar and 'SLOVENSKÝ ŠTÁT 1939' (Slovak State 1939) or similar text. The designs include portraits of national figures like T.G. Masaryk and M.R. Štefánik, along with diverse landscapes and city views.

Issued in 1939 following the dissolution of Czechoslovakia and the establishment of the independent Slovak State under German protection, these provisional stamps served to validate existing Czechoslovakian postage for use in the newly formed state, marking a significant political transition.
