I'm still somewhat dazzled, there's still a bit of packing to be done and I must get to bed so I can arise at a bastardly early hour, so I'll keep this short and leave the full charity auction write-up for next time. Suffice to say:
The sketchbook sold.
It reached the guide price of £600, which I had thought was a bit too optimistic.
Then it kept going.
And going.
The winning bid: one and a half thousand pounds.
I am staggered, emotional and rather deliriously happy.
MOOOOOO!!!
