Alan Cristea Gallery, 31 Cork Street, London W1 (0171-439 1866) 18-23 Dec
IT'S OVER 40 years since Richard Hamilton first defined the principles of Pop Art. He's now a very grand old man of the British art scene, yet somehow he has always managed to stay pretty close to the avant garde. One of the reasons is that he has always been one for technology - especially in print-making, where he has never shied away from using television and video, and especially computers, to continually push the boundaries of what passes for graphic art. This latest exhibition, consisting of some 20 or so works made over the last 30 years, is appropriately titled New Technology in Print and stands as a testament to his ongoing originality.
