They called it the "Jim Lee experience". Once you got in line, you could look at artwork and original panels that he would sell. Some were as high as $85K! They also had some stuff from his own collection that wasn't for sale. Very engaging people working with him that would give you some background on the pieces.
I got the impression that it was a family affair, he had about 4 different people helping him.
Lee and I spoke about the late '80s to early 90s run at Marvel. He said that was the real "golden age" of comics. I agreed with him. McFarlane's Image indulgence started the 90s downfall. McFarlane was always a better artist than storyteller, but I enjoyed some of his Image work. But it accelerated the mediocrity of the industry overall (Liefeld!), and ultimately diluted the comic industry by flooding distributors with tons of copies of books that wouldn't sell.
I've heard McFarlane is a gracious person with fans, but really comes off as arrogant and off putting with others in the industry. I'd love to meet him. Can't tell the history of comics over the last fifty years without him, Lee, Claremont, Byrne, Miller, Morrison, Shooter, and others.
