It has previously been accepted that these globes marked MPS were manufactured by the workshop of Johann, Carl and Peter Bauer in Nuremburg, due to the similarity (in some cases identical) between miniature globes found with the initials MPS and JBB, CB, or PB. However, the current example is unusually large for an MPS globe, and also bears marked similarities with the work of the C. Abel-Klinger Kunsthandlung, also working in Nuremburg. A similar globe in a card drum-shaped case, by the Klinger workshop, passed through these rooms in November 2000.
