Shaded park benches and a row of parked cars line the plaza before Matamoros' arcaded Palacio Municipal in this real photo postcard, the city hall facing a square that has anchored civic life since the town's founding in 1774. A chalked arrow on the cobblestones is a photographer's own location mark, rarely visible in finished postcards.
