My internationally famous pictures from Germany
First it was the Australians who wanted to use my picture of the Frankfurt airport in some kind of German course materials they were developing.
Now, a geology professor in Georgia (the U.S. state, not the country) writes:
If you ever wondered why you bothered to put a picture of a recycling bin in Berlin on the Web, let me say I'm grateful. I'm putting together a lecture on environmentally sensitive lifestyles in Europe, and I have several pictures of my own for that purpose. However, I realized I needed a picture of one of those train-station-style recycling bins. You saved me, and your picture (with attribution) will appear in my lecture tomorrow.
