Paul, I do know the normal prices of some things... and I could see that 00s had been added. Those uber-rich just don't know they're being taken to the cleaners. They seem to place the value of what they pay onto a bit of tat, not what it should be.
If it's expensive, it must be good! They're just clueless.
For example, there was a fairly straightforward looking, slightly lumpy rectangular vase - thick, with a misty sort of blue centre. Nothing particularly stunning. It did have Per Lutken's pawmark on it, but I ain't paying £1500 for a boring, waterstained, scratched lump like that, even with a pawmark. (it was one of the rather cheap things there)
