"Simple mistake" my a*se, just ignorance and inefficiency, symptomatic of much that goes on. Was not a SINGLE London-savvy person involved in the graphics of this ad? Utterly disgraceful. What is going to be done to compensate HMS Belfast?
The time spent massaging that image should have been used to make the Shard look finished. There's enough urealistically slick computer generated images around to help them with that, which is in effect what they have turned that photograph into anyway - another fantasy. Perhaps the Shard is too sacred to 'touch-up', but it's ok to obliterate the battered Belfast.
