A nice one from Calpe, Spain
. In fact the only one I've ever seen was a Banksy on Bruton Lane, and that probably only remains as its too high up to easily paint over, seen here from page 6: https://www.cyclechat.net/threads/street-art.221565/post-4909879
. EDIT-no its not, its actually over 50 years old: https://www.smithsonianmag.com/arts-culture/who-really-invented-the-smiley-face-2058483/
