Of course, the lessons I did learn in his classes were priceless, and even though I eventually gave up on the dream of drawing comics, I have repeatedly found his teachings on storytelling to be invaluable in my own humble efforts as a writer (and in my brief career as a comic book editor) over the years.
Joe Kubert was an astounding artist and storyteller who contributed so much to the medium. He will be greatly missed by the multitudes who appreciated and enjoyed his work, and my most sincere condolences go out to his family and friends.
R.I.P. sir - and much thanks.
