a page from a private book
Entering my name for a Google search about it, I was surprised to see that the rightmost picture displayed by bing.com was from a private book of mine published with Lulu (Saint-Petersburg 2007), a diary on a trip to Russia that was never made public, but gifted to a few friends. You see, while the other pictures are the front pages of some of my books, this particular one is actually the last page of the diary.
Now, how could it have been made public? Very puzzling.
