The Book of Signs, originally published in 1934 written by Rudolph Koch (who was also a typographer and did a few nice fonts) is largely a book you can download for free if you subscribe to some reading site (who charge $).

But Google books will show you several pages from the eBook, along with explanations of symbols.

Just remember that with Frances' tutorial—and just a lot of tutorial we have here—you're not limited to a target shape the author provided! I have the hardest time convincing people who have bought a book I wrote (so why am I complaining?!) that you don't have to start or stop at the file I provided. Use you own along with the principle I shared with you.

Improvise.

Innovate.

Recreate.
