Wow, I didn't know it was that easy to draw like Joe Kubert! Thank you for posting this, those Limited Collector's Editions were gems, weren't they?
There were a number of of How-to-Draw features in these oversized treasures by the definitive artists on those characters, including Carmine Infantino doing The Flash, CC Beck demonstrating the right way to do the original Captain Marvel, and Alex Toth's model sheets from SuperFriends!
It's not hard ...all it takes is practice! Good luck! lol
