My friend Harry Harrison is the political cartoonist for the South China Morning Post in Hong Kong. He's also the illustrator of many, many children's books.
He has a picture in an exhibition called Animal Crackers at The Cartoon Museum in Little Russell Street, London, which runs from 25th July until 21st October 2012. The Cartoon Museum is near The British Museum in Bloomsbury. For details of opening times, location and prices, check out the 'visit here' tab at http://www.cartoonmuseum.org
If you can't get to The Cartoon Museum, or if you can and you want to check out more of Harry's work, you can see his illustrations online here. They're amazing - he's very talented.
