N.d., circa 1890. Closed, oblong, 13 by 23.5 cm. Chromolithographic map and views of river constituting a 22 panel leporello. When fully stretched open, this leporello, or panorama, measures 264 by 23 cm. Together with a booklet with explanatory text (Erläuternder Text) rendered in English and French as well as German. This booklet is 31 pages. The color palette of the panorama is somewhat austere, with dull greens and browns dominating, and touches of red here and there. It is very much in the dark Romantic, Wagnerian Ring aesthetic. There are a total of 58 inset views, including the two larger views, one of Cologne, the other, of Mainz, at each end. The panorama would have been sold as a souvenir to tourists who typically were doing a Rhine cruise. Light wear.
