Found this wallpaper while doing my routine search for new and exciting Hawkman imagery. There's no mistaking that this is Hawkman from Superfriends, with the extended, uh, thingys on his helmet and primary coloring. I have to say though, as few times as he appeared on the show, other than the elongated face of the helmet, Hawkman's animation model is pretty sweet.
The artist, one Mike Peters, has other wallpapers available, including others of this style for other Superfriends characters, including Aquaman, Flash, and Black Vulcan. Basic, yes, but I think it has a sort of goofy charm to it.
