Recently I have been painting watercolour postcards for general sale, for £3 a card sent through the post. I enjoy creating them, and I am starting to build up a stock that I hope to sell in the Cambridge Art Salon shop. However, I also paint cards to order. For some time I thought my masterpiece would be the rabbit that was torpedoing a fox, but the same delightful client came back to me with an even better order; cows exploding because their overcoats are full of methane.

Biggles and Daisy the horrified cows are now in the post. Speed well, little bovines, and bring the horseradish sauce.
