The most important basis for any successful transaction involving a work of art is its provenance, the history of its making and passage through different hands. In order to be an effective investigator into the source and provenance of individual artworks, it is essential to engage curators, registrars, databases and artists to locate accurate and updated information. Jeffrey Thomas has assembled a time-tested, discrete and globally connected network of collectors, dealers and auction houses to gather the necessary information.  


  • Selection of artists to be involved in planning and/or creating site-specific artworks.

  • When clients wish to resell works of art, Jeffrey will consult with them on market analysis and the best strategy for divestiture. Jeffrey will act as the agent or administrator of the trade. Consultation may be for individual works of art or for an entire collection.
  • Research into provenance title and ownership
