Two postcards from the Imperial War Museum which consists of five locations, three in London. The most recent of the five is the Churchill War Rooms, opened in London in 1984.
Both of the postcards are reprints of "public service announcement" posters of the day. I can understand about eating carrots for your eyes, but it's not clear to me what "Save Bread and you save lives" and "Serve Potatoes and you serve the country" mean.
Any thoughts?
P.S. It's Postcard Friendship Friday. You know what to do.
