U.S. Postage Stamp Centenary (1847-1947) 3-Cent Stamp

This is a United States postage stamp commemorating the centenary of U.S. postage stamps, issued in either 1947 or 1948. The stamp features a central design depicting significant modes of communication and transportation throughout the period 1847-1947. On the left side, within an oval frame, is a portrait of George Washington, and on the right, within a similar oval frame, is a portrait of Benjamin Franklin. Between these two historical figures, there are illustrations of various conveyances, including a small, early locomotive (train), a sailing ship, and an airplane, symbolizing postal delivery methods over a century. The denomination '3' appears in the top-left and top-right corners, while '1847-1947' is printed at the top center. Below the main design, the text 'U.S. POSTAGE STAMP CENTENARY' is clearly visible. The stamp is blue in color and features perforated edges, characteristic of postage stamps designed for separation from a sheet. The condition appears to be relatively good, with no obvious major tears, creases, or heavy cancellations visible from the image. The perforations seem intact, and the imagery is sharp, indicating reasonable preservation for its age. The overall aesthetic is clean, suggesting it might be an uncancelled or lightly cancelled stamp, though the reverse side is not visible to confirm absence of adhesive or postmarks. It exhibits the typical characteristics of a mid-20th-century commemorative postage stamp.
