All my paintings, large or small, are sold with a Certificate of Authenticity.
The Certificate of Authenticity guarantees the authenticity of the painting you purchase directly from me or from a gallery representing me. It verifies this by providing the details of the work and is dated and hand signed by me.
Below is an example of the Certificate of Authenticity you will receive. Note that the border of the certificate is actually a section of the painting itself and a picture of the entire painting is shown on the certificate. In addition, the certificate includes a QR code as an additional security feature that, if scanned with your smartphone will take you directly to my website.
