Woman’s Most Difficult Problem, 1937
“Even the most fastidious woman may cause embarrassment to others at certain times,” according to this 1937 advert for sanitary towels. Hooray for Dr Van de Velde and his “Vanderised Towels”, then. Wouldn’t want anyone to be embarrassed by us, would we?
Having said that, I am in favour of no chafing if that was previously a danger, pre-Vanderisation.
I’m presuming they’re using the word “prophylactic” as meaning “disease-preventing” here. Otherwise, it’s quite an impressive claim.
