And yes, it’s for real.  From a customer review:

The five sections explain all you’ll need to know to about classifying carts, section two lists Class A: False Strays, Types 1-11 and section three Class B: True Strays, Types 1-22. Each type gets a page with a cool photo and details about what to look for. The longest section is four, titled Selected Specimens, with more than three hundred photos of battered and dead carts in the environment, I think the ones in snow look best and they are categorized according to either Class A or B. It won’t surprise you to know that the author toiled for six years creating all this.

The design and printing of the book is fine and the author takes a pretty good cart photo. The only thing missing, I thought, was some reference to their manufactures, there can’t be too many and they most likely all have unique features. This would certainly have added to the thrill of spotting a Class B, Type 11 (train damaged cart) made by A N Other Inc.
