Switzerland 1921 20c Helvetia Tête-bêche Pair

Switzerland · 1921 · 20c

The stamp depicts a seated allegorical figure of Helvetia, facing left, holding a sword and shield with the Swiss cross. This is a tête-bêche pair, meaning one stamp is inverted relative to the other, with a '20c' overprint.

This stamp is part of Switzerland's long-running Helvetia definitive series, featuring the national personification. The '20c' overprint likely reflects a postal rate adjustment, while the tête-bêche pair represents a significant printing variety.
