Had an appointment with Dr Hutton, Marshall's chiropractor today as I've been in a sorry state lately. He was fabulous and a really nice guy. As I relaxed on the rolling table at the end, this notice was on the ceiling. He said the building was also a chiropractor's office when he bought it 15 years ago and this was on the ceiling then. And it's never fallen down. It looks to me as though it's been up there since the 70's, loved the retro cartoon look.
