Deborah Lundbech's photos with the keyword: London Underground 1960s

Inspired by JFGryphon's post. This was brought over from England for me by our (Woodlands Avenue) previous neighbors, who visited us in The States in 1970. It's a longish heavy duty plastic bag lined with cloth. You can see all the stops clearly, in the larger sizes. How would it hold up as a guide today, British friends?
