However, as the postal system expanded and became increasingly efficient, the utilization of postage stamps gained ground, ultimately revolutionizing the way people sent and received mail. Over the years, the design and purpose of postage stamps underwent significant evolution, reflecting changes in American society and culture. In the early days of postage stamps, the primary motif was the portraits of renowned Americans, paying homage to the nation’s founding fathers and notable figures. Subsequently, the thematic scope broadened, encompassing images of historic events, national landmarks, and the natural wonders that define the United States. Today, the USPS issues an extensive range of stamps, from the ordinary to the extraordinary, including commemorative stamps that celebrate influential individuals, significant historical events, and cultural icons that have left an indelible mark on the nation.
