I was a huge HB heroes fan back in the day, especially the first wave (most of them below) — Space Ghost, the Herculoids, Bird Man … it was comic book genius.
Alas, eventually HB lost its way, battered both by anti-violence activists and more success in doing silly/fun heroes and, eventually non-heroic cartoons that were all modeled after Scooby-Doo.
I had my revenge, though: forcing +Kay Hill to grow up watching this stuff (along with, of course, Jonny Quest).
Anyway, I'd love to see a serious treatment of these characters, with modern art, as presented here by Mardem Moura.

UPDATE: Oooh, t-shirt? Hmmmm … (http://www.redbubble.com/people/dinshoran/works/15654934-hanna-barbera-super-heroes?p=t-shirt … tempting, if I had use for any more t-shirts …)
Oooo. Didn't realize it was available as a t-shirt. Awesome. Will have to write about this for Geek Alerts.
