SF & More. . .
David A. Hardy is best known as an astronomical or space artist, but as a freelance (since 1965) he has turned his hand to many other areas of art and illustration, from fine art to advertising and work on TV and movies. He has also written and illustrated several of his own books, and a novel.
The main area is of course science fiction or SF (for those in the field, the term 'Sci-Fi' is reserved for the media rather than literature – but Hardy has worked in all of them including fantasy!)
