DC Comics, Adventures Of Superman # 504, Comic Book (First Printing) from 1993.   COMIC HAND SIGNED BY COVER ARTIST & WRITER KARL KESEL!   (see my other auctions for more signed comics & cards).  Comic was hand signed by Karl Kesel at the annual Connecticut Comic-Con 2016, held at Mohegan Sun. It comes with a POA (Proof Of Authenticity).

Holo-Graphix foil cover!

Comic is in a VF/NM or better condition. 

To eliminate some concerns as to the authenticity of an autographed item, I include in most cases, what I call a POA (Proof Of Authenticity), which usually is a copy of the flyer addressed to me and the page listing the artist as a scheduled guest. While I provide certificates for some items, my experience at conventions is that, the table selling certificates is far removed from most of the artists. As a result, the signing isn't witnessed by the sellor of the certificate, so how can this be guaranteed authentic? Another source of certificates are those printed up by the sellor who guarantees authenticity!!! Just a thought not to get hung up on certificates. I have been selling signed items on ebay since December 4, 1998. I haven't had any problems with authenticity in all that time! I personally guarantee that the signature is authentic, and was signed by the creator, witnessed by me.
