We went away from Sparks’ parents house, when we last visited, with this curious object.
It is a pie carrier that belonged to his grandmother, and so could date from the 1930s. It looks and is put together just like my tiffin cases, but on a larger scale. We wonder if perhaps the tiffin case design wasn’t based on these pie carriers… or if they aren’t both descended from a common ancestor. It would seem so.
