Its fun to discover where your images are been used and I keep a image list on my website (see 'commercial') of some interesting finds. Because my images get sold around the world I didn't expect to be walking back home the other day, and see a 6ft poster of a conceptual image I created, in the window of a local store.
Many other examples of my images in use can be seen here. http://www.simonbrattphotography.com/#!commercial/cfvg
If you spot one, let me know.
