Certificates of authenticity are proofs or receipts that follow an artwork or piece of autograph for life. It is a tool to help potential buyers, collectors and investors to determine if the item is authentic or not. Often times a certificate of authenticity will include information such as

• Artist name
• Title of work
• Year of completion
• Dimensions
• Medium
• Autograph information such as who signed it
• Edition number if applicable
• Special instructions
• Artwork image
• Statement of authenticity

The certificate of authenticity is an official document that proves the work/autograph is genuine and authentic. Ideally, it should accompany every work of value or signature, regardless of whether it is sold or not.
