Painted in warm ochres and deep forest greens by artist Georg Rothgeb, this charming artist-signed chromolithograph shows the medieval skyline of Idstein in the eastern Taunus hills: the stout round Hexenturm (Witches' Tower, a surviving 13th-century keep) rises at left, while the sprawling Renaissance-Baroque Schloss — once the residence of the Nassau-Weilburg dynasty — commands the hillside at right, with a misty glimpse of the Taunus ridgeline and a tiny castle silhouetted in the far distance. The blue-and-gold heraldic lion of Idstein gleams in the upper right corner. Sent from Idstein on 30 March [190?], the card carries a 5-Pfennig Germania stamp and was addressed to Herr Hermann Mutz in Hamburg-Eilbek, Hasselbrookstraße — with a personal message lamenting that the writer is stuck in Idstein with illness ("Plagegeist der Karte") but hopes to come to Hamburg soon by train through Homberg. Publisher L. Klement of Frankfurt a.M. issued this as Nr. 7 in their Künstler-Serie: Die Burgen des Taunus.
