I've never seen Space Angel but I've always thought that Alex Toth's designs for the show were ahead of their time. They remind me of more adult artwork, what with the shapely tight-fitting suits, the rotund chap's enormous gut, the gorgeous gal and the hunk's the eye patch. It has a sort of French look too, altho' I don't know why.
Toth's ships are wonderful too.
The Starduster is just superbly simple.
As is this gorgeous yellow plane with an array of tanks close by.
There are many fans of Toth's ships online and here's just one, The Land of Nod, who has researched them describes them much better than I can.
Do you like Space Angel?
