Just been told that a painting I was given the very first edition of a few months go had two of the subsequent editions (from a very limited run) sell at auction last night for about 15 times what mine was bought for. It stands to reason that my painting would sell for more. So now I know it's only a matter of time until I rip it or somehow throw tea at it.

What is the most valuable thing you own? You can say a house or car if you want, but I'd prefer we excluded them because they're boring. I also don't want to hear any sentimental pussy crap. I'm talking cash value here.
