Pleasure from pictures

Letter to The Guardian 

Pleasure from pictures
From Mr Jeremy Moon
Sir, writing in your Annual Financial and Economic Review III (September 27) about paintings as investments, David Fanning says: ‘An added attraction is the pleasure which pictures can give as they hang on the wall growing in value almost daily.’ As a painter one thing worries me about this remarkable insight. Is the pleasure derived from looking at the painting, or from simply watching it ‘hang on the wall growing in value almost daily’? More or less like mushrooms or chinchillas I suppose. 
Yours faithfully,
Jeremy Moon
