Portfolio with name and title in gilt to front board, no publisher or date [ca. 1920], tri-fold flaps inside containing four photographs, 11.5 x 17.5 cm, depicting Beethoven-focused artworks by Hans Schliessmann, each mounted to larger rigid pages measuring 25 x 32 cm. The portfolio flaps inscribed by W. Lowitz and dated April, 1927, evidently marking the Beethoven centenary. Mounts toned, portfolio worn and stained. Rare. No copies located in Worldcat or in the trade. Never having seen this volume or found any record of its publication, we cannot state with complete confidence that it is complete as issued, though there would only be space for another print or two if ever there were more than the four now present. The images are wonderful. One clearly depicts Felix Weingartner as he conducts the Eroica from atop a high note which springs from the composer's fertile scalp!
