What can be valued?
I can examine single items as well as sets or collections. Available information on period, origin, condition, provenance and composition helps refine identification and valuation.
How to prepare your request
A few clear photos, a general view of the object and, where possible, close-ups of signatures, marks, inscriptions or labels allow a first analysis. For a large collection, an appointment can be arranged to examine the pieces on site.
Purchase and travel
After identification and valuation, a cash purchase offer can be made. For large collections, a free visit can also be arranged.
