A pretty good book with some fun lessons rooted in simple geometry and clear instructions. The perspective lessons at the end are a bit more complex, but they're still good instructions. I'd say back this up with other books on the fundamentals (including perhaps Loomis' other books on figure drawing), since formulaic lessons can become a crutch, but this book is still rooted in a lot of those basics, so you won't be lead astray.
It's unfortunately got some racist caricatures that don't at all age well, with a couple bits that might be sexist by today's standards, but maybe I shouldn't be that surprised, since this book is nearly 80 years old, and some of the 20th century's more brutal, trying lessons hadn't been learned yet (WW2 and its horrors were only just getting started, and the Civil Rights movement was still 15 years off) I call these things when I see them, but I wouldn't throw the baby out with the bathwater with these older texts.
It's a quick book too, especially if you're just doing an initial read through. Less wordy and more pictorial than Loomis' other books. It's old, and I can think of some professors and professionals who might tsk at some of these formulas, but it still has some really good nuggets of knowledge.
