The use of contrasting types of amber, the architectural form, and the carving style of the foliate panels are virtually identical to several caskets tentatively attributed to the Königsberg amber worker Georg Schreiber. Particularly relevant is a casket in the Schatzkammer der Residenz, Munich (Reineking von Bock, op. cit., pp. 96-8, figs. 131-2 and 134), which is itself attributed to Schreiber on the basis of its similarities to five surviving pieces signed by him.
