Note: After being so perplexed by how out of date the faces were, I looked at the "about the author" text on the cover and found out the author died in 1981 at the age of 90. This is apparently a new book using his sketches, which explains a lot. I'm leaving my original review as follows since it will help determine if this is a good book for you.
This is a good basic drawing book to learn how to pretty easily draw faces but it is straight out of the 1940's and 1950's in terms of the faces. It's almost comical how out of date these people are. Think Leave it to Beaver and black and white private detective movies. All of the subjects are thin, white, conventionally attractive looking folks with trim haircuts, ties, fedoras, bows in their hair, etc. other than one black child who looks like he's wearing a newsboy cap and a few older folks (one might be Mother Teresa?). The only man who looks non-white reminds me of a villainous foreigner cliche of an old Man From U.N.C.L.E. episode. Makeup is minimal on women -- again, think of the stereotypical housewife or secretary from the 50's and you'll get the idea.
The book is in black and white with the exception of colorful boxes of text. It is 40 pages in total.
This will be a good primer on drawing faces with scale lines and such. It shows alternate angles and a variety of old fashioned hairstyles. You'll need to look elsewhere for diversity of models, body size variations, or modern makeup, hair, hat and dress styles.
I read a temporary digital ARC of this book for the purpose of review.
