I can supply a certificate of authenticity for any work that is directly acquired from me. These are digitally signed with an embedded certificate to ensure they are authentic and unaltered. You can verify them yourself using a free pdf reader that supports digital signature verification, like Adobe Acrobat Reader and my public certificate key (to download click here and extract the key from the zip file). Instructions for how to use this key to verify the document are available from Adobe or perhaps more helpfully, a modern AI chat tool.
