A Christmas card designed for the Dub Smugglers, a Manchester sound system, built by taking a Renaissance nativity, an Adoration of the Magi, and quietly swapping the saints and shepherds for Manchester sound-system faces, adding a stack of speakers up in the corner where a holy light would be and the word Manchester across the sky. A proper old altarpiece, crewed by the local sound-system crowd.
The joke only works if you do it straight, match the painting exactly and let the wrong faces do the talking, so it takes a second to notice a rig of speakers has replaced the holy light. A card like this is a good end-of-year job: no brief beyond make us laugh, and a licence to deface a masterpiece in the nicest possible way.
