I learnt quite a bit by doing this drawing: Your heart is basically a pump, some chambers, valves and tubes, a bit like a central heating system in a house, but pumping warm blood around your body rather than warm water around your house. Available now as a A2, super high quality Glicee print BUY HERE or go to my shop. In the past I have produced screen prints of my work, but found this to be quite a wasteful process, so I am making this print (and others) available as a digital print. They will be made and shipped to order by the good people at Printer of Dreams in Hackney. That way only the prints that I sell will be printed meaning no paper or ink is wasted.
