Commodore 64 owners past and current will recognise this design as the C64 Owners Manual.  Design is printed on one side of the mug.

Please note that while this mug is safe for use in the microwave and dishwasher, not washing in a dishwasher will prolong the overall life of the design.  Also note that the listing image is illustrative of the design - each mug is printed to order so there will be minor variations in positioning.
