One of my first capitalist ventures was buying 8 x 10 glossies of the Beatles and selling them to my classmates in 1963, I think. I know I was on to them about a year before everyone else.
Unfortunately, I lost most of my collection in some move or other (prolly from my parents' place in '70). The one magazine I kept was a bunch of wonderful informal black and white shots in a studio, I think. Unfortunately, I can't lay my hands on it right at the moment, though I'm sure I still have it somewhere.
