Republic of Czechoslovakia, 20 korun, 1919 Provisional issue (using a 2 January 1913 Austro-Hungarian note). The first Czechoslovakian banknote issue. The 1919 provisional issue of Czechoslovakian banknotes used an earlier Austro-Hungarian Bank issue. By affixing an adhesive stamp equal to 1/100 the value of the note (i.e., 1 koruna = 100 haleru) to the left front side, this served as validation of legal tender status in the Republic of Czechoslovakia. Following currency reform, the first regular issue banknotes were printed with a date of 15 April 1919.
