As I was having a look through the book I had a double take at the surfboard fin page. Is it me or is there more than a little similarity between the images in the book and the images I created for the fin section on this very site.
Here's the first one

OK, pretty basic image, not really many places to go with this representation. Don't really have an issue with this one, and if it was just this image I would not have looked twice.
Here's the second.

This one is remarkably similar. Almost exactly the same image.
Here's the third image

The legend has been swapped but the colours are exactly the same.
Is it me or are the book images blatant copies from this site?
Here's a snapshot of those two pages from back in 2007, courtesy of the wayback archive.
