The photo of the table runner is the very same as shown in the book "Pinwheel Party". Go to Amazon.com and search for the book, then under the book image, click "See All Product Images". Your table runner is right there, so I imagine they have the pattern in the book. If you don't want to buy the book, try your library. Alot of times, if your county's branch doesn't have it, they can request the book through the state or national system. This might help if the other sources don't work for you. :)
Wow, you all sure are block identifying experts!!! I will certainly come here when I need help with something like this :) I looked for this block in a book with 4500 blocks in it, didn't see it.
