Walking along Quaker Street, Spitalfields yesterday we encountered this strange memorial attached to a tree. 'Every hour, one abandoned dog disappears forever,' claims the label, which hangs from a ghostly white dog lead.
The message highlights the plight of abandoned animals, which (according to the Mail) are put down at the rate of one an hour in the UK.
The white dog lead recalls the ghost bike campaign, where white bicycles are left on the scene of fatal road accidents involving bicycles.
We're not sure who's behind this latest campaign, or if other ghost leads have been left around town. If you've seen one, do let us know.
