Q: I am trying to find info on this book. There is no date. It has 26 illustrations with a coverslip (color)?

A: Your book was first published in 1918. Your copy however is a later one. The 1918-1920 copies of this book had yellow lettering.

You can date your copy with the information here:

It is neither rare nor valuable.
