Shoot, I was 15 then. Yeah, I was big into Depeche Mode... probably my most valued posession at that time would have been the porno mags I borrowed from my dad. Funny how things worked out!
Actually, at that slice in time I was a phat comic book dealer traveling around to conventions buying, selling and trading. Really, it was my first most noteable experience as an entrepreneur. I inherited a huge comic book collection from my dad who used to advertise in every one of them in the 70s...
So, my most valued posessions from then that I still have now would be a couple thousand comic books left in my collection from the 70's that have his ads in them. Many have his photo even.. Like the one below, those are the 'money' shots from the 60's.
