So as the title says, what do you collect and don't say clothes, shoes unless there is something special about them.
Me, my dad had a huge collection of collector glasses, wine, beer, etc.
Mum sold them off for a nice profit about 15 years ago and I started to collect them in the last 5 years, I'll buy a bottle of something I don't drink if its got a free collector glass or pot with it.
Cameras, this has been something I've done since day dot.
All up I have about 600 cameras, ranging from 1945 to today, mostly film but also some very early digital SLR's and some flashes that are at least 50 years old. My best friends boss owns a huge camera store and when I threw her engagement party here he was amazed at the cameras. When I bought the house I'm in I had to get the shed rebuilt so they can be stored. Also have 1 rule with the cameras, they must work, even the box brownies.
