I'm not a big comic book reader, but everyone I know has told me to pick up Watchmen.
I went into a local comic shop today (Samurai Comics in Phoenix) and picked up a copy. A guy at the counter grabbed my book, opened it to a page with the arrest profile of Walter Kovacs and told me the guy who's thumb prints appear on the page is in the store to sign autographs later in the afternoon.
As polite as I could I asked if those were his thumbs, he said they were and then signed the page for me. I thanked him, shook his hand and left.
Main plotter and coordinator and writer and whatnot.
