Rotterdam's Nieuwe Haven shimmers beneath a full moon in this luminous nocturne, the waterway's dark surface alive with reflected gaslight as an early electric tram rounds the quayside and tall-masted sailing vessels lean at their moorings — a romantic, lithographically hand-colored scene that captures the Dutch port city at the cusp of its 20th-century transformation into the world's busiest harbor. Published by the celebrated Leipzig firm Dr. Trenkler Co. (catalogue no. 20869), masters of the moonlight "Nachtaufnahme" postcard genre, this card deploys their signature technique of tinting a photographic base with vivid nocturnal blues and ambers to spectacular effect. The back carries the full UPU "Briefkaart / Carte Postale / Algemeene Postvereeniging" bilingual header in red, and the single undivided address side — "Zijde voor het adres bestemd / Côté réservé à l'adresse" — firmly dates this to the pre-1907 undivided-back era. Unused and remarkably well-preserved for its age of 115+ years.
