Just some cool artists I dug up when I went to the library the other day that I wanted to share, since I hadn't heard of them (except for Polacco).
Barbara Macdonald - found her in a little book called A Golden Age: Visions of Fantasy, Australia's Fantasy Illustrators: Their Lives and Works
Rentoul Outhwaite (same book)
Kay Nielsen from A Treasury of the Great Children's Book Illustrators
Patricia Polacco from The Art of Reading
Richard Egielski (from same book)
