Q: Hello, I obtained this book from an estate sale (The Young Engineers in Mexico). Was wondering what the worth was and if it is a desirable collectible. I have attached photos for your review. Thank you very much.

A: This book is part of the Young Engineers Series (http://henryaltemus.com/series/series34.htm). This is part of the third format of this series and was published in the mid-late 1920’s. Without a dust jacket these Altemus juvenile series books seldom sell for more than a few dollars. Because your book is not in the best shape, you most likely will have difficulty selling it at any price.
