8vo. 12pp. In sheets as issued, with paper spine. Ownership stamp of Dr Hans Semper (Semper’s son).
Offprint of the article on Semper (1803-79) in Allgemeine Deutschen Biographie, signed by the printed initials H.S. and therefore presumably by Semper’s son Hans, to whom this copy of the offprint belonged. It is certainly very well-informed on Semper’s career and publications.
