I have taken the liberty of calling this dog ‘Toby’, as opposed to ‘Punch and Judy puppet’, since this is the name usually given.
Toby was made by Harry Vernon (c1920-30), and is now owned by Peter Blake. He was part of a marvelous Barbican exhibition, entitled ‘Magnificent Obsessions’ (2015), which showed stuff collected by artists.
The square was cut from an exhibition leaflet, and the photograph was taken by Justin Piperger.
