Working on an extension of the Pentone system at the moment. (We had to do mugs eventually.) Got the first proof back from the printer – a friendly place in Stoke-on-Trent where they call you 'me duck' and mugs are 'beakers' and they don't do Pantone Cool Grey 7, they do 'charcoal'.
There'll be a set of four mugs available to buy online, hopefully a few weeks before Christmas. So stick the kettle on and watch this space.
