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 have bought a couple of mugs and can confirm they are good quality. My artwork was true to the original and in the mug in this photo, although a sepia piece and therefore dark, the clarity and detail was not lost in the printing. The mugs came well packaged in a solid box.
