Are you talking about THAT exact vase, or one like it?
That one looks to be big and rather competent - they're ALL different, and the price should reflect the individual piece. I disagree strongly with John regarding that price being high, though - if it's as big as that one looks, and as wide, and as well shaped, and artist signed and dated, I reckon it's a bargain.
Prices do vary, before the recession, artist signed Fish vases were regularly reaching £200-ish, things have dropped off a bit with the crunch.
