This striking blue definitive features the iconic Moscow Radio-Television Tower (Ostankino Tower), symbolizing Soviet technological progress and nationwide broadcasting power. The tall vertical composition emphasizes the tower’s impressive height against a dramatic sky, a classic example of mid-century Soviet architectural pride. Issued as part of a standard postal series, the 10-kopeks value saw wide everyday use, making well-preserved copies desirable. Clean perforations and deep ink contrast add strong visual appeal for thematic “communications” or “architecture” collections. A solid representative piece for Cold War era or USSR infrastructure specialists.
