1965 Switzerland Matterhorn Centenary Commemorative Stamps

This set features two used postage stamps issued by Switzerland (Helvetia) in 1965 to commemorate the 100th anniversary of the first ascent of the Matterhorn. The stamps are presented on a philatelic album page with descriptive Dutch text. The first stamp is a 10-centime denomination in dark teal green and white, while the second is a 20-centime denomination in a deep reddish-purple or maroon and white. Both stamps utilize a vertical orientation and feature a graphic, stylized artistic rendering of the Matterhorn peak. Each stamp is cancelled with a black circular date stamp (CDS) that appears to bear the name 'Zermatt', which is the iconic base town for the mountain. The stamps are rectangular with standard perforations on all four sides. The paper of the album page is a white grid pattern with black printed text. The condition of the stamps appears to be 'fine used'; the perforations look intact and the centering is relatively even for the period. There are no visible signs of significant creasing, staining, or tearing on the face of the stamps, though they have been hinged or mounted to the album page. The printing method is rotogravure, typical for Swiss issues of the mid-20th century, showing high-quality ink saturation and crisp lines in the mountain's silhouette.
