A gnarly, hollow giant frozen in silver gelatin — this real-photo postcard captures the legendary 2,000-year-old sweet chestnut (Castanea sativa) standing at Gasteil near Prigglitz in Lower Austria, its massively fissured trunk split open like a cathedral door, with a pastoral hillside and farm buildings fading softly into the background. The "Edelkastanie" (noble chestnut) of Gasteil is one of the oldest documented trees in the Austrian Alps, a living relic that predates Christianity in the region and drew tourists and naturalists well into the 20th century. This card was mailed in 1963 by a sender writing from the Gasthof-Seminar Sulzhof, Prigglitz, addressed to a Frau Eckert in Vienna I, Maria Theresienstraße — a chatty, ink-filled personal note covering nearly the entire message panel. A postage-due stamp (violet handstamp "1.50" and red boxed machine mark "0150 nachzahlen") indicates the card was underpaid and the recipient was charged the balance, a charming postal irregularity that adds to its documentary value.
