I was approached (and subsequently sold) some rights to an image. I didn't even think it was a particularly good image, but it somehow filled the bill for a company that tests high-end photocopiers. They're going to use it as a test image. It won't be used as marketing material or distributed. It will be printed and likely shredded. Over and over. So, a likely topic... what "weird" sales have you been approached about or made?
