F. W. Bossert (Otto Bossert´s Wwe)

Bernardstrasse 26, Offenbach am Main, Germany. Friedrich Wilhelm Bossert took out a British Patent No. 1919 dated 2 August 1864, for a musical photograph album having the musicwork mounted in the spine. Bossert´s business was established in 1859 and was still in existence as late as 1909, presumably run by his son, as manufacturers of musical photograph albums. (Ord-Hume, Musical Boxes, p. 295)
