Phil & I visited a walled garden today, that we have driven past quite a few times. This old GPO telephone box was by the entrance gate! Usually, particularly in pictures of London they appear as red & all over the country when they were in use, they were red. As you can see, someone has painted this one a Kermit green! I love it!
