Review of "The Frazetta Pillow Book," artwork by Frank Frazetta



Review of

The Frazetta Pillow Book, artwork by Frank Frazetta ISBN 0878162534

Five out of five stars

 The artwork in this book is billed as the kind that you look at when you are tucking your mind into bed, but only if you are a mature reader. It is a combination of nature and nudes, the characters are forest creatures right out of Northern European fairy tales, yet they are almost always naked. One of the best ones has a naked Irish “man” with exposed genitalia sitting on a toadstool hoisting a large mug of beer with a lot of healthy foam on top. From the look on his face, it is not his first drink.
Both genders and all sizes of creatures are depicted. From the context, it appears that some of them are meant to be human. There is a bit of sexual innuendo, but it is quite tame. This book of fairy tale artwork for adults would also fit well into children’s books if it was cleaned up a bit. The art in it would appeal to children as it is consistent with what they read in many of their books.
