Comic book retailer and founder of Free Comic Book Day, Joe Field, writes,
Back before Flying Colors Comics opened, when I was still working for KJOY-AM Radio and doing publicity/advertising work for the convention that would become WonderCon, I did some video interviews for a local cable access TV show. I think we completed two episodes and didn't use any of the footage we shot in 1988 at The Wonderful World of Comics Convention (phew! No 'wonder' we shortened the name!)
So one of those interviews, with the late Mark Gruenwald, who in 1988, was Marvel's Executive Editor and a writer of a couple of titles. Mark's untimely death in 1996 at the age of 43 left so many his friends and family shocked. He died of a congenital heart problem, even though he was seemed to be in great health and was said to be be doing actual cartwheels in the Marvel offices just a week before his death.
