50/50 Haleru Surcharge on 15h and 20h Newspaper Stamps

Czechoslovakia · 1927 · 50h on 15h & 20h

This is a rare error stamp from Czechoslovakia, featuring a 50 haleru surcharge printed over two different newspaper stamps, a 15h green and a 20h carmine. The surcharge itself is inverted, making it a significant philatelic variety. The base stamps depict a stylized falcon, a symbol of the Sokol movement.

Issued during the First Czechoslovak Republic, this inverted surcharge error occurred during a period of economic adjustment and overprinting of existing stamp stocks. Such errors are highly sought after by collectors as they represent a rare mistake in the printing process.
