Back in the Sixties I got some weird little plastic toys one Crimbo called Wall Walkers.
It was a sort of double plastic frame with a smiley face at the top and suckers at the bottom. It was purple.
Once set up on a window it could 'walk' down it by flipping over itself a bit like a flat slinky!
I loved that wallwalker and thinking of it takes me right back to Christmas '69!
Do you remember them readers?
