Wow, very impressive! I'm a life-long ERB fan too.
How are the actual JC stories themselves? Worth reading? I have to admit I'm a bit underwhelmed by the cover art, except for the cool painted cover. This is very different from the Tarzan series, which for the most part featured great painted covers (except the early issues, which had pretty poor line-drawn covers, and all the photo cover issues, which I don't collect).
Thanks! They are pretty good reads, if for no other reason than that they are ERB adaptations so they had a good foundation with which to start. The Funnies series is much better than the three FCs though, IMO. The Funnies issues, I think, do a better job of capturing the look and feel of the novels. The FC issues are a little too G-Rated if you know I mean.
The best art, by far are the John Coleman Burroughs issues (Funnies 34-56) and the best cover I think hands down is Funnies 36 (below), also by JCB, though I like FC 488 as well. The art for the three FC issues is by Jesse Marsh whom you should be pretty familiar with from the Dell Tarzan series - he's competent, but not spectacular.
