Bournville

Quite an uncommon promotional jigsaw puzzle, probably dating from the 1930's, which features Cadbury's Bournville-Factory in a Garden works, first established in 1879 by George Cadbury and which later, following the acquisition of more land, grew to become the village of Bournville, complete with schools, parks and leisure facilities.
The cutting style and the box labelling lead me to a belief that this puzzle was cut by the same cutters as the Expert puzzles, one example showing this similarity can be found at Dare He?
A second version shows slightly different box styling, so probably indicates a second print run of the puzzle. Both carry the same piece count and price.
