McCartney Times

This book by Terry O’Neill is being published either in March or Jun of 2023 depending on which entry you may look at on Amazon UK. Terry passed away a couple of years ago. However I have a signed EMI invitation for some Beatles-related event he did. I want to make the signature into a bookplate to put inside the Terry O’Neill  book retrospective of his Beatles photos, making it the only signed copy in the world. Does anyone know how bookplates are made or where they can be made? Would appreciate any help you can provide me with this issue as I want to be able to do this correctly and not mess the book up. Thank you and I look forward to your reply. The signature is shown below and the rough dimensions of the signed piece. Thank you all for any help you can provide to me in my quest!
