Here is the inked version of the Captain Marvel pin-up:
Together with the inked pin-up, I got a copy of Charles' "Carnival: The Human Hourglass". Charles still has a few copies available after APE and he is selling them through his BLOG.
The coolest thing is that for just a few dollars you get the ashcan AND Charles does an original sketch (knowing my love of the 70's cosmic Marvel universe, Charles did a Captain Marvel for me). "The Human Hourglass" is a great crime noir story, well told, and drawn with care. I enjoyed it and I recommend it...a lot :)
