There are ceramic mugs available via T-Shirt Studio (who ship internationally as well as the UK) featuring my artwork.
They are a standard 10oz size. The artwork is printed on both sides of the mug.
I bought a mug and can confirm they are good quality. My artwork was true to the original and, although a sepia piece and therefore dark, the clarity and detail was not lost in the printing. The mug came well packaged in a solid box.
