I am (clearly!) surprised and delighted to have finally spotted my poem which has been riding the rails of the London Underground for the past six months. I live in Norwich and visit London rarely. Lots of people have sent me photographs of their sightings, and now finally with my own eyeballs! The link to the poem without my photobombing phyzog, is here: https://poemsontheunderground.org/the-square-of-the-clockmaker
