Auctions offers certification through Collectors Proof. As always, all autographed items I sell were personally witnessed - by myself - being signed by the artist, writer, creator or celebrity in question. Further, art sketches - and most published pieces of original artwork I sell - were obtained directly from the artists themselves. Not only is this a record of the guarantee of the authenticity of the item, traceable back to its original source, but it also maintains a permanent web-based record of ownership accessible from any computer with internet access.It also allows the current owner to print out a hardcopy of a Certificate of Authenticity (COA), if desired, but without the need of actually having to protect physical paper certificates from loss or possible destruction as the documentation is permanently maintained and available online. Please note- the guarantee that I sell only signatures I personally witnessed the signer in question autograph is real regardless of whether or not you opt for the authentication service through Collectors Proof.
