Cobblestones, whitewashed medieval façades, and a slim Gothic church spire rising at the end of a quiet lane — this evocative real-photo-style view of the Margarethenstrasse in Krems an der Donau distills the timeless character of the Wachau, the UNESCO-listed Danube valley whose wine-covered terraces and ancient towns have barely changed since the Habsburg era. Published by K.L. Wien as part of their Series XVIII and printed on a distinctive textured stock that gives the image a painterly depth, this card was never mailed — the reverse is entirely blank save for the printed title and a penciled dealer price (ATS 120 / €10), suggesting it passed through a collector's hands relatively recently. The Wachau region draws intense philatelic and topographic postcard interest, making even modest unused examples desirable to regional specialists.
