Michael Preuß & Co. G.m.b.H. published a very large music repertoire of artist rolls for the 88 upright piano from 1923 onwards. All artist rolls could also be ordered as 'combined', i.e. with additional perforations for the automatic art piano. Many good pianists have recorded music here, including Oswin Keller and Michael von Zadora. This catalog has about 200 pages. In the first section the pieces of music are listed by composer, in the second section by title. We offer a pdf copy of this rare catalog for research purposes for EUR 60,00.
