I photographed this fantastic sign today after going past it so many times on the bus. It’s just by the Geoffrey Museum in Shoreditch and is covered at this time of year by a big tree. I had to do a bit of monkey-style climbing to get onto the roof underneath, hence the odd angle. It’s an absolute classic (Perfection, indeed!) but I haven’t found any further information yet. I’ll have to get back on a winter morning for another shot.
