Javamom has a great post about what Charlotte Mason education is about--AND she includes some photos from a 1930's Parent's Review magazine (with ads). I have a bound volume of the 1903 Parent's Reviews, and they didn't have any graphics or ads like that at all back then! PR had really changed its look 30 years later--and yes, those little tidbits are fascinating. Like looking at WWII ladies' magazines--the ads are the best part ("cheer up our soldiers by wearing our brightest shade of lipstick!").
(Thanks to Mother Auma who pointed me in Javamom's direction today.)
