Vintage Postcard Fragment with Swiss Postage Stamps

This item is a remnant of a vintage postcard or envelope, physically consisting of a rectangular piece of heavy-weight paper or cardstock that has been torn roughly on the right side. It features two distinct Swiss postage stamps and handwritten elements in purple ink. The first stamp, a 40c value, displays a modernistic graphic design with stylized colored squares (green, yellow, red), characteristic of late 20th-century philatelic design. The second stamp is a 10c red stamp depicting a transport vehicle, likely from the 'Switzerland by Rail' or a related heritage series. The paper itself is an off-white or light cream color, showing signs of aging and wear including fibrous edges from the tear and a faint rectangular postmark cancellation overlapping the 10c stamp. Centrally located on the fragment is vertical cursive handwriting, possibly indicating an address or name such as 'Schmitt' and 'Richterswil', which are common in German-speaking regions. The handwriting reflects a traditional script style common in the mid-to-late 20th century. The condition is poor due to being a fragment, but the stamps and ink remain vibrant with minimal fading.
