fifties illustration techniques

I have been searching the web for what seems like forever to find something meaningful on the techniques of fifties storybook style illustration. I finally found a true treasure island of insight techniques, expert explanations and excellent examples: John K's Blog. Blessed be the good man.
He posted an interview with one of comic's greatest artists; Art Lozzi. This interview covers about the whole subject of illustration techniques and it sure answered a lot of maddening questions i had about how to obtain certain effects (like the grainy shading that is so typical of the "Golden Book" style. (Partly this involves acrylics, rollers and sponges)
Thanks John, and Thanks Art!
