These are NOT caricatures! I find that the more accurate I am, the more insulted people become. Besides, I'm not very good at them...

You tell me all about the target - likes, dislikes, hates, car, family, boozing habits, hobbies (if that's not the same thing) travel, job etc and I do a pencil visual. You shout hooray and I ink in and colour the personalised cartoon masterpiece. 

You frame it (or I will) and the lucky person gets a fab cartoon to hang in reception (or loo) for ever more.

Easy peasy...
