This idea has been made real
Laurence and Angela are well-known for their witty, beautifully crafted miniature automata, which continue to not only delight dolls-house enthusiasts but also have a large following in their own right, most automata are available as framed versions to put on your wall. They also craft perfect miniature replicas of Victorian and Edwardian household ephemera, from the very high-end Gent's shaving stand for use by the Lord of the manor, to brushes, kitchen implements and needles threaded with cotton.
The Personless Dog Walker is a track that you attach your dog to and it can take itself for a walk when you aren't able to!
This ingenious idea was brought to life by St Leger Miniaturists in the form of this delightful mechanical model!
The entire object is only 3cm wide and 2cm tall!
