A vivid bird's-eye sweep down Twentieth Street toward the north end of downtown Birmingham, Alabama captures the city at its industrial peak — streetcar tracks glinting in afternoon light, early automobiles dotting the intersection the back-panel copy proudly calls "The Heaviest Corner in the World," where First Avenue and Twentieth Street each anchored a skyscraper on all four corners. The linen-finish lithograph blazes with the saturated ochres and brick reds characteristic of E. C. Kropp's finest Depression-era production, and a postmark of July 13, 1938 ties the card to a specific summer day when someone named L.B. dashed off a practical note promising to be home by afternoon and asking the recipient — a Mrs. Tom Brown on Military Road in Columbus, Mississippi — to contact Mrs. Sanford or Mrs. Roy if Saturday morning help was needed. The 1-cent Franklin green stamp (Scott #632) paid the domestic postcard rate of the era, and the faint machine cancel from the Birmingham, Alabama post office is legible through the ink. The detail inset reveals the slender white column of what appears to be the Empire Building rising behind the massive Brown-Marx Tower, a skyline snapshot now almost a century old.
