Actually these books are likely counterfeit, being produced overseas and sold on Amazon as the real deal. It's easy because neither the publisher nor Amazon (nor the customer for that matter) can know that someone listing a product is shipping a fraud.
That sounds reasonable, sure. You might also try contacting the author directly. Authors tend to know way more about their books than the person answering your email at the publisher, and certainly would have a good idea what their print editions are supposed to look like. I've actually found emailing book authors about their books in niche fields to be usually really easy and interesting in its own right.
