South Africa King George V 1 Shilling Inverted Watermark

South Africa · 1927 · 1s

This definitive stamp features a portrait of King George V, part of the 'Union pictorials' series. The design is notable for its bicolour printing, with the King's portrait in a central vignette. This particular stamp is famous for its error, where the multiple springbok's head watermark was applied inverted.

Issued during the Union of South Africa period under British rule, this stamp represents a significant printing error that created one of the country's most sought-after philatelic rarities.
