This is one of the quintessential London landmarks - the red telephone booth. While most have been replaced, you can still find them scattered around town. We discovered this one last night, while on a walk, just a few blocks from our home. Waverly was very excited to open the door. I don't think she got that there was a phone. She just loved the little room randomly placed on the sidewalk.
Charity, I listened to you. I put my camera in my bag for just this sort of photo. Thanks for the advice!!
