An old post from my previous and now defunct blog, but Jennie Harbour's work is definitely worth revisiting:
There seems to be very little information available about Jennie Harbour, not even her date of birth/death. I’m not so keen on her color illustrations but I love the black and white pieces, they are brilliant in their simplicity, especially the compact and detailed silhouettes. Below are some selections from My Book of Favorite Fairy Tales, published in 1921. All images from Project Gutenberg.
