These designs are now available on a range T-Shirts in different sizes for men, women and kids at Uncle's Shop. Mugs are also available. Choose from the category index on entering the shop.
I am happy to create a T-Shirt which has a fan's favourite character or characters on at no extra charge. Just let me know which your favourite illustation is (book and page number and description) and I will make a T-Shirt with it on available at the shop.
