In reply to Indy:
This is taking things to extremes, but gives an idea of the level of work that can be involved:

There are some pictures of the process here:

Then you can encounter 'unknown' artists in pop-up art galleries. I've bought a couple of pieces like this; one, a hand-drawn original, acrylic pen on wood panel, £260, and two, a small (8" x 5"), multi-coloured, framed linocut print for £25. The second piece was from the artist, at an 'art fair' in the local town hall at xmas. She was surrounded by a lot of tat, and her obvious talent stood out. But she didn't seem to be aware of her talent.
Having bought the first piece, I deliberately wandered around a snooty gallery with it under my arm, turning my nose up at the inflatedly priced, comparatively talentless daubs they had on display.
Oh, and some fantastic limited edition photographs.
It's all about perceived value. I buy stuff I think is a fair price, based on the skill and effort I think went into it. As soon as galleries are involved, that goes out of the window...
