This is what I found in the fourth position in the fourth folder -
an old Abbatt jigsaw from my childhood.
Actually it was probably bought by my mother for her Nursery school
which was run from our house in the late 60s and early 70s.
Paul and Marjorie Abbatt were pioneers of children's educational toys in the 1930s.
They opened a shop in Wimpole Street designed by their friend,
the modernist architect Erno Goldfinger.

I wasn't overly keen on jigsaws.
They spelt boredom on a Sunday afternoon listening to the syrupy medleys on Sing Something Simple.
