All limited edition prints include a signed certificate of authenticity that shows the edition number and other information.The edition number is shown differently depending on the material: - Paper prints include the edition number hand-written in the lower left corner. - Metal prints do not show the edition on the front of the print. Instead, I provide a label that can be adhered to the back of the print with all of the certificate information. - Canvas prints do not show the edition number on the print. It is shown exclusively on the certificate.
