This brief book - or should I say, "these brief books?" - is/are as interesting for its/their physical arrangement as anything else. If you turn the book upside down and backwards - it's a new book. One side giveth the Holy Commandments of God Almighty regarding typography, and the other side giveth Satan's dissent to the same.

There are a few mildly ungrammatical sentences - for example, "Thou shalt apply as many different typefaces as thou wanteth to!" doesn't parse. The -eth suffix is third person, when the sentence needed a second-person conjugation.

But for all that, it's still a pretty amusing book. And trust me, fun books on typefaces are comparatively few.
