The 100th Anniversary of Swiss Stamps in 1943 is a significant event, commemorating the issue of the first Swiss stamps (the Zurich 4 and Zurich 6) in 1843.

The primary and most collectible item issued by Switzerland for this centenary was a special Souvenir Sheet (often called a Jubilee Block).

🖼️ Key Feature: “Stamps on Stamps”

The most notable aspect of this issue is that the commemorative stamps were designed in the “Stamps on Stamps” topical style, faithfully reproducing the famous Zurich 4 and Zurich 6 Cantonal stamps of 1843, which were the first stamps issued in Switzerland.

The original stamps were:

Zurich 4: A block of four with the number “4” printed in black on a red background.
Zurich 6: A single stamp with the number “6” printed in black.

The 1943 centenary stamps are highly sought after, especially the Souvenir Sheet (Michel Block 9 / Scott B132), as it marks a major milestone in Swiss postal history.
