In my KS3 Toolkit book for the GA, "Look at it this Way", there was an activity called 'First Class Landscapes' which explored the design of stamps to show a future landscape. Since then, plenty of stamp sets have emerged, and we are now about to have a really nice looking set of coastal landscapes.
