Artist and writer Anita Willets-Burnham took two trips circumventing the globe, first in 1921 and again in 1928, and both times she brought her four children. She wanted to show them the world outside the classroom.
In 1930, she wrote about these travels – and how to afford them – in a memoir-meets-budget travelogue called Round the World on a Penny. Above is an image of the 1940 reedition of the best-seller, which boasts probably the best book cover in history, esp. the little monkey in the bottom right.
That is all.
