All originals are one of a kinds completed by Rob Tillberg. Each comes with an Archival UV Inhibiting varnish applied and a Certificate of Authenticity. Due to our prices being lower than any of our online vendors or brick & mortar galleries, you'll have to contact us for them. We apologize for the inconvenience. That said, purchasing an original can be a big decision and almost never completed by simply clicking "Buy Now". We usually create a relationship with our customers throughout the process. Providing them with additional images, videos, and even mock-ups of the piece in their home. So introduce yourself & let us get to know each other!
