The loo wall in the Sun & Doves in Camberwell is a constant source of delight for me. They’ve papered it with illustrations from old books and magazines, which is great in its-self. But it also acts as a versatile canvas for pub wits.
The two examples below show the downright intriguing (what exactly is a ‘shrub rocketer’? And who is Spike?) and the schoolboy classic: the penned-on knob. Last seen appended to the head of Jean-Claude from La Rochelle in my GCSE French text book, Ticolor 3, it’s an all-time, world beating visual gag. Enjoy.
