I have looked quite a bit and done a few searches... sigh What is the url for sending in a hardcovered book? what about a magazine like Life? Thanks
Why would you want to send those in?
I am slowly selling my collection. I have several signed books that would probably do well in ebay with an authentication. My Life magazine has Ali and Frazier autographs on the cover... I think an authentication would be helpful to sell.
The form is here, under Submission Form: https://www.psacard.com/services/autographauthentication
Page 4 has return shipping references to books and magazines.
