Reading the marks on the work

On the back or the stretcher, labels, stamps and inventory numbers are so many links: they point to galleries, collections, exhibitions, carriers. Photograph them all, even damaged.

Do not remove any label and do not try to clean them: their condition is part of the evidence. The expert will know how to date them and match them with the archives.

Keep, always

Putting together your provenance file

  1. List the known owners

    From oldest to most recent, even approximately.
