I got married in 2004 and as my new wife and I were packing up my (quite awesome) solo apartment to move into our house, she took the task of packing my bookshelf. As you can all relate - if there was a great comic artist, one of his/her books were on that shelf. She opened and flipped through many of the hardcovers/trades as she was packing them. When she got to Vol. 1 of Batman by Neal Adams she asked "...why is the artwork in this book so much better than everything else on this shelf?"
I can't remember when I told Adams that story, but he had his usual wry smile and said "Your wife has very good taste!"
He was a legend in every sense of the word. When you saw one of his covers, you grabbed it. This is devastating news. Thinking of his family and loved ones and while sad, we'll always have his work. And if they are still making comics in 100 years, some kid will see a reprint of a GL, X-Men or Batman and say "...woah...who is this guy??"
Godspeed Neal.
