DMcG - I think I acknowledged the artistic value, as Dave did by putting his money etc

Sort of. But you also said 'Let it be' because you believe it to have no financial value. But many here see the artistic value as sufficient grounds to oppose letting things go, whereas you appear to regard the financial aspect as the deciding factor.

We differ, that's all there is to say, really, so I don't expect to post further on this aspect, especially as people like Richard just above are making essentially the same point I was but rather better.
