South Bank Exhibition Festival of Britain, 1951, The (250 piece)

The larger 250-piece interlocking plywood jigsaw puzzle, cut as a promotional souvenir for the South Bank Exhibition, part of the 1951 Festival of Britain celebration. Although not credited as such, from the cutting style involved, the puzzles were almost certainly made by AVN Jones.
The artwork is signed R. Tilbrook, possibly Reginald Tilbrook (1898-1976), understood to have been a bus conductor before being discovered as an artist!
Also included with the puzzle was a Key Plan, helping to identify the various exhibits on the site.
