Last week, I've bought a used book, and only when I brought it home, I noticed that there are two photos inside it. One shows flowering shubs of someone's garden, and another is a snapshot of an Asian-style watercolour. There's a name on one of the photos, but no address, and they don't look very important, so I'll probably throw them away.
Also, as I was leafing through the same book later, I found a theatre ticket from 2009 December.

So far this is the oddest thing I have found in a used book.

If you are interested here is a link to an scanned image of the postcard i found.
