Abstract Circular is painted on a stretched canvas with staple free sides, so is ready to hang. Professional quality acrylic paints are sealed and protected with a UV varnish. Artwork is signed on the front on the lower right. It will be signed in pencil on the back with name, date and title and stamped with my website address on the stretcher bars. The Certificate of Authenticity, hand signed by the artist, is digitally stored with a registration number. Once you recieve the Certificate, directions will be included as to how to lock in your assigned numbers. This is for your own protection if required for insurance purposes. If you have any questions, please contact me at pbrooke@mac.com. Please Note: There might be some color differences due to different monitor settings.
