A pencil sketch of Spider-Man by Gabriele Dell'Otto that was published in the Marvel Heroes Portfolio was used at a convention inking panel for a number of artists to ink over.
From the top (via ungoliantschilde tumblr):
- Original Penciled Artwork by Gabriele Dell'Otto
- Inks by Andy Brase
- Inks by the late Tony DeZuniga
- Inks by Geof Isherwood
- Inks by Craig Hamilton
- Inks by Terry Moore
- Inks by Atula Siriwardane - the inks that Atula Siriwardane did are not from the inking panel. he posted his inked version on his website after hearing about the panel.
- Joe Rubinstein also inked the piece, but I am still looking for that version.
