Today and for the past 25 years, give or take, I've loved the expressive way Joe Kubert illustrates. I didn't always feel this way about his work. If I remember correctly it was the cover to All-Star Squadron #2 that changed my mind about Kubert's illustrations.
I was looking at it for the umpteenth time when I began to see things in the lines that he put down on the page that I hadn't seen before: motion and expression. After that I went back and re-examined all the other covers to All-Star Squadron that Kubert did. Some I liked more than others but the switch had been flipped. I got it. I understood why people liked his drawings so much or at least learned to appreciate them for own reasons.
