Bernie Wrightson was the first comics artist whose work I loved. Oddly, I don't mourn the artist. I mourn the lovely man who told bad jokes.

I loved Bernie's great art, but loved Bernie the man, my friend, even more. His horror was so powerful because it came from an empathic soul https://t.co/0Xb9OHSlAf
