On March 6th, 2003 the Swiss Post Office issued a 70 Swiss cent postage stamp with embossed braille to celebrate 100 years of the Swiss National Association for the Blind (SNAB) and the Swiss Library for the Blind and Partially-Sighted.
The stamp is red with a large number 70 in another shade of red which can easily be overlooked. "HELVETIA 70" appears in white writing along the bottom edge. In the middle the number 70 is embossed in genuine braille that can be read by touch.
This individual stamp with selvage is mint, never hinged and in pristine condition. Photo is representative and selvage may differ.
