2 December 2015: The Gurlitt Task Force announced the identification of a Menzel drawing, 'Inneres einer gotischen Kirche (Kirche in Hofgastein)' ('Church in Hofgastein'), as the fifth looted work found in the Gurlitt collection. The drawing originated in the collection of Dr Albert Martin Wolffson of Hamburg and was sold by his daughter Elsa Cohen to Hildebrand Gurlitt on 31 December 1938 with nine other works by Menzel just before she fled Germany. The drawing is on lostart.de at http://www.lostart.de/DE/Fund/478264
The Task Force's press release, issued only in German, is available here. It makes no mention of whether the Task Force has traced the heirs, is already proceeding to restitution, expects the heirs to contact them, or etc. The drawing had already been identified as from the Wolffson collection by other researchers.
