It would depend on where one applies for either a credit card or admission to law school.
I’m not familiar with Mass Brothers, but my first credit card was issued by Garfinckels in Washington DC in 1966. It could also be used at a number of other local department store chains that existed then (Woodward & Lothrup, Raleighs, Hechts, etc). Later in the 60s I got Lord & Taylor, Carte Blanche and Amex. That was long before 1982.
My husband’s former mother-in-law graduated from GW’s law school (also in DC) back in the 1930s. The Ivies didn’t admit women at all till @ 1970, so those that have law schools (other than Cornell which was always coed) would have denied women admission before then.
I would say my experience was the rule and not the exception, just based upon my own observations, few of which I remember or document. I am certainly not a crusader or angry feminist by any means. I went to law school to take care of myself in a better job than say, teaching or nursing.
