Five crisp black-and-white vignettes of postwar Heerlen fan out against a jet-black mount in this striking Dutch multi-view real-photo postcard — the busy Station square with its Jugendstil railway building at upper left, the modernist slab of the Hoofdbureau O.N. Mines administrative headquarters at upper right, the leafy Oliemolen roundabout at center, the bustling Saroleastraat shopping street at lower left, and a sweeping aerial of the Flatwoningen residential rotonde at lower right, with the town's heraldic shield inset below. "Groeten Uit Heerlen" — Greetings from Heerlen — announces the card in bold white lettering, a pride of place that reflects Heerlen's remarkable mid-century transformation from small Limburg market town into one of the Netherlands' most industrialized cities on the strength of its coal mines (the Oranje Nassau Mijnen, whose headquarters appears here). Published by Gebr. Simons of Ubach over Worms and certified "Echte Fotografie" (genuine photograph), this is a handsome artifact of the Dutch coal-boom era, unused and remarkably clean.
