Additionally, the photos (the few that there are) are formatted badly: every one has a cut off caption box as shown here.
I don't know why people produce books like this. It's not that the content is bad, but I just can't see many sales coming out of it, especially for 21 scant pages at that price. Why not throw that up on a free website and use Google Adsense as I do here? No, you wouldn't get rich from that, but you'd probably make more money than trying to sell it as an ebook!
I'll provide the Amazon link, but honestly I wouldn't bother with this one.
Note: All my coins are in a safe deposit box. I keep nothing in my home.
