I have just started selling on zazzle.co.uk. Its a great place to buy original artwork on posters, canvas, clothing and mugs - or just create your own, either customise the products from the art supplied by the artists on zazzle, or make your own posters and canvases from photos.  Great site, hight recommended for artists.

Here is a espresso mug I created in May 2016.

See it in 3 different styles here 

The original artwork is 60"x48" acrylic on canvas;
