Not to be trusted. Lost all the important written historical provenance that was attached to existing frame. They just threw it away !!!! They were specifically asked to keep and attach to their new frame. Find someone else for your framing.
I have been using Gunst Framing for many years now and highly recommend this business for service and value. Mr Gunst is a true artisan. I trust his framing suggestions as he has a keen eye for enhancing artwork.
