Real photo postcard (RPPC) of Calle 6a (6th Street) in Matamoros, Tamaulipas, Mexico, looking down the commercial main street from an elevated vantage point. The view shows an ornate Beaux-Arts style building with a decorative roofline — identified as the Palacio Municipal — at center left, lined storefronts with awnings, period automobiles parked along both sides, a decorative lamp standard in the foreground, and pedestrians on the sidewalk. Radio towers are visible in the mid-distance.
