I have about 20k Magic:The Gathering cards from when I was a Big Brother many years ago.
I also have a small collection of bolt action military surplus rifles.
Neither is convenient to photograph at this time.
Right now I'm sitting on the porch collecting mosquito bites...
I don't collect anything for collecting's sake. I have many of a couple things, though. Fountain pens, ink, pipes and tobacco. Some audio equipment that's piled up over the years from music production, performance, etc...
Seems to be a high proportion of musicians here. That's probably not a coincidence.
Ha. When I lived in Texas, the Army Surplus store had oodles of 7.62 in stripper clips and bandoleers. They didn't shoot for shit out of the M44 I had, but man could you blow through some ammo on a budget.
