Let me see what I can contribute... I don't have too many scanned items to share, but I think you might find these of interest.  When I buy original pages directly from the artist I like to get a picture of him holding the piece...

Here's Terry Moore holding the original art for Strangers In Paradise #22, page 17, which I purchased from him during the 2010 New York Comic Con...


Archie Comics artist Fernando Ruiz holds the original art for the 7/4/10 Archie Sunday newspaper strip (2011 Wizard World Big Apple Con)... I bought three pieces from him - this, two original dailies (drawn on one comic-book-sized page) and an Archie comic books page... he offered to sign them but I asked him not to - ironic considering how much I love autographs - but I felt signing them would destroy the integrity of the pages as actual production pieces, since the signature did not appear in the final published piece and would have been added after the fact...




When I get sketches at cons and such I also like to have the artist show off the finished product... here's Rick Parker proudly displaying the Harvey Pekar sketch he created for me at the MoCCA Sketch Table during this year's MoCCA Art Festival...




World Wrestling Entertainment Hall of Famer Jerry "The King" Lawler proudly shows off a self-portrait he did at last year's New York Comic Con...




Finally... the below image, from this year's Wizard World Big Apple Con, was just too cool a photo op for me to ignore... don't know how much it really "qualifies" contextually for this thread, but that's okay... first I want you to look at the photo, then I'll tell you what's going on...



Okay.  In the background, waving to the camera, is Papercutz editor-in-chief Jim Salicrup. (I know him personally, so that's why he's waving to me.) You probably recognize Jim's name because he used to be an editor at Marvel Comics. In the foreground, the piece with "NIGHTMARE!" in large letters, is the original splash page to Fantastic Four #248, November 1980.  The page includes the credit box, which includes Jim Salicrup's name as editor.  Since that dealer's table was so close to Jim's table at the con and it was logistically possible, I thought it would be cool to get the man and the page with the man's name on it in the same shot.

Incidentally, the asking price for that page was $3,500... I think the fact that the guy who did the actual drawings was a fellow called John Byrne, and not so much Jim's being the editor, was the primary factor used by the seller in determining the price.

I did not buy it.
