Aug.1, 1975, a 2 color for a HVAC company, dark green and black on white Healthknit t's. (they were 3 packs, with tape on the shoulders and cardboard inserts). I got a day's pay, I don't know what my boss made... One of my lasting memories from back then was you had to buy a dozen of a color of a size from the wholesalers. Then one day, Eisner Bros. in NYC came up with the idea of case, dozens and singles. Within month, all the wholesalers were doing it.
At least that's how I remember it, it was almost 37 years ago, I was 23.
