This is an illustrated fifty-two-page, soft-cover square booklet published by the London
Museum in 1973. I think it was connected to an exhibition but there is only one one reference to this in the text. The seven chapters (Home, Spare time, The Nation's health, Politics, London grows, People at work, The capital city) each have an interesting essay mixed in with an excellent selection of photos and graphics. Well worth searching out if you are interested in the Thirties London life. Worth saying that it originally cost five shillings.
