Life, May 24, 1943:

It's intriguing that if "father walks to work and Bud bikes to school", that means it's okay to put the family car "up on blocks" -- because certainly no one else will need to do any driving for any reason whatsoever.
And I notice that it's
father who walks to work, but
Nora (not "mother") who handles "the week's washing" -- presumably the housekeeper/laundress.
