Neal Adams son, Jason Adams, posted at the Collector’s Society Message Board on the thieving that took place at the San Diego Comic Con this year. In addition to one of his own statues walking off, so too did two of his dad’s comics.
I found that the thief came back to steal 2 things from my father worth a couple hundred dollars each. He had a Superman CGC graded comic which he had drawn an original Superman portrait on and a Green Lantern with an original Green Lantern and Green Arrow portrait on. Both were on stands and both were gone while lower priced items were put in their place.
