An interesting week for people who enjoy drawing and jokes because of two excellent exhibitions which are due to open.

The first, on Thursday, is a huge Heath Robinson show at the Cartoon Museum on Little Russell Street, near to the British Museum. Robinson is most famous for his quirky mechanical contraption jokes and this will be a very popular show.

And on Friday, the irrepressible Tim Benson launches Iraq in cartoons. This show will be packed with the best of editorial talent in the country, including Tanya Tier – a highly talented and hardworking satirist who organised the recent Birds of War show.
