INFORMATION - without any need to ship the work to us:

No matter what kind of information is required, we shall first of all need a good photograph (of the reverse side too, if there is a stamp, an inscription or a drawing – a photocopy will suffice), a complete description of the work and all available details, including  provenance. A good photograph of your work is imperative for our archives, especially when it comes to publishing a new c atalogue raisonnĂ© or subsequent additions.

PHOTO-CERTIFICATES - for work shipped to us:

For photo-certificates we shall first of all require a photograph and then – after mutual arrangement – the original work here in our archives for a certain time. Personal delivery of the work to be examined will not be possible.

Please send your work of art and two photographic prints (18 x 24 cm) with your pro-forma invoice addressed to us and marked “Zur Begutachtung” (“For Expert Examination”) through your shipping agent for temporary exportation from your country.  Please note: works on paper must be unframed and freely accessible on the reverse side. Your shipping agent will provide for temporary exportation from your country to Switzerland (so as to avoid costs and difficulties when the work in question is returned to you).
