Empire Defence

Once more the artist Margaret Dovaston features in a c1930's plywood jigsaw puzzle, this one almost certainly cut for Fortnum & Mason, one of London's most famous department stores by AVN Jones to their Delta Fine-Cut standard.
The 350 piece Victory puzzle The Conference features another very similarly-themed period scene by the same artist.
