I just started collecting in January. What I have showing is a wall in my home office. Nothing spectacular as far as what comics are on display. I'm afraid to put any expensive key issues up on the wall because of earthquakes . However I have about 20 comics that I'm waiting from CGC to put on display on another wall that were CGC witnessed signed by Stan Lee, Neal Adams, Brian Michael Bendis, and Jim Starlin.
There is a sketch by John Romita Jr., original art from Marvel Adventures: Spider-Man #29, Production art from The Amazing Spider-Man #214, X-Files comic signed by David Duchovny, and original theatre poster of Star Wars the Force Awakens. I'm mainly a Marvel fan but I also collect DC and Valient.
