Art Gallery 'X'mas Cards

Several galleries sent me e-cards or messages this Christmas, via their mailing lists. There was a mad one from aas (an ephemeral performance art collective, see http://aasgroup.net/) see below. Charlie Smith (the London gallery) included an image of Christ by painter Gavin Nolan (see bottom). I believe the painting features in the book The Face of Jesus by Edward Lucie-Smith, which I might try to take a look at. The thing that strikes me is that it's ugly. The geometric lines are interesting, part of it almost suggests a star of David. I could also see the lines as drawing a visual bridge between the portrait and the viewer.
