Like peace, love and lemon-meringue pie, ‘public art’ seems unarguably attractive. Who but a philistine curmudgeon would deny the populace access to the immediate visual thrills and the enduring solace of beauty that the offer of public art seems to promise?

Public art is surely a democratic benefit. Never mind that in the past century its most forceful expression was the grim and malignantly deceitful narratives of Soviet socialist realism, with their ruddy-faced, grinning and buxom tractor drivers disguising a more real reality of starvation, intolerance and torture.
