Czechoslovakia 1919 500d on 1000h Newspaper Stamp Inverted Overprint

Czechoslovakia · 1919 · 500d on 1000h

This is a Czechoslovakian newspaper stamp originally valued at 1000 haléřů, featuring a design by Alfons Mucha. It was revalued with a red '500d' overprint. This specific example is a famous error where the overprint was applied upside down.

Issued shortly after Czechoslovakia's formation in 1918, this stamp represents the early postal history of the new nation. Overprints were common during this period of transition to adapt existing stamp stocks to new currency values.
