King Farouk 10m Brown and Deep Blue, Inverted Center

Egypt · 1938 · 10m

This definitive stamp features a portrait of King Farouk of Egypt. It is famous for a rare printing error where the central portrait vignette is inverted relative to the surrounding frame. The frame is printed in deep blue, while the portrait of the king is in brown.

Issued during the reign of King Farouk, this stamp is one of the most well-known and sought-after error stamps from Egypt, created when the sheet was fed into the printing press upside down for the second color pass.
