Collection of International Commemorative and Standard Postage Stamps

This philatelic collection features three distinct sets of postage stamps mounted on protective black cardstock within a professional stamp album page. The leftmost item is a British 'One Penny' red-brown stamp, likely a Victoria era or early 20th-century issue, displayed in a small mount. The center piece is a horizontal pair of South West Africa stamps, featuring a bicolored design in olive green and reddish-brown, valued at 20 cents/pence each; they appear to be in unused, mint condition with well-defined perforations. The rightmost stamp is a prominent Indian commemorative issue featuring the portrait of Mahatma Gandhi, valued at 1 1/2 annas, printed in a sepia or brown monochrome. This Indian stamp includes a significant vertical selvage at the bottom bearing the serial number '074239', which is a desirable feature for collectors. The stamps generally exhibit sharp edges and clean printing, suggesting they have been well-preserved away from light and humidity. The protective mounts signify a serious collector's handling, minimizing hinge marks or skin damage to the gummed backs. No significant foxing, tearing, or fading is immediately visible across the three specimens.
