I actually access to some old Mar-vell comics, as it happens, including the first issue featured in this video (with the green and white costume).
My dad has about 300 comic books from the late 60s/early 70s - mostly Amazing Spiderman, Fantastic Four, Avengers etc, and also 10 or so of these. I was completely obsessed with the collection as a kid, but not particularly with these - I recognised the images in this video but can't remember Captain Marvel so I guess they weren't that great.
As for DC's Captain Marvel, I'd never even heard of him til I saw a friend playing DC vs Mortal Kombat, but what with only having read a load of comic books from 40 years ago I've not really had much exposure to comics as a whole. Cool episode though, and fun to have Bob explain something about comics of which I'm at least slightly aware.
