Staff Letters At Walthamstow Central

Staff Letters At Walthamstow Central

If you look closely enough at many underground platforms, you’ll see a range of “hidden in plain sight” signs and features. I took this photo of mailbox for Staff Letters at Walthamstow Central Station. What are your favourite hidden or secret sights on underground platforms?

This photo was taken during my Victoria Line Walk, in support of Bowel Cancer UK to see more photos from the walk you can visit my Flickr page.
