I overall had a great time at the expo. A lot of fun to chat with the guys at the tables that were there mostly to show off their stuff or take offers too good to refuse :) You just don't get to see that great stuff at any other time.
What was very disappointing was to arrive early and get one of the first entries into the show, only to see dealers walking away from Mignola's table with stacks (one very fat stack) of art as the doors opened. Some of it is already showing up for resale on their websites. If I had know that was going to happen, I probably would have skipped the show, or at least lowered my expectation of being able to buy Mignola art. All that was really left (I was 5th in line) was sketches and covers.
