For the thousands of students who visit Auschwitz-Birkenau every year with the Holocaust Educational Trust, approaching the gates and setting eyes on those infamous words, "Arbeit macht frei", is invariably a moment of solemn reflection. The wrought iron sign has become a symbol of evil, grim shorthand for the sadism of the camp. Yet the sign is a replica, because two years ago this week the original was stolen to order. It was recovered but, for security and to avoid further damage, it has not been re-hung.
That crime naturally prompted both disgust and bewilderment. Perhaps we should not have been surprised, given that the theft took place against the backdrop of a thriving market in Nazi-era items. Last month, the press reported on the sale of Hitler's monogrammed bed linen, while, last week, a brass desk-set apparently made for him was auctioned in New York for a staggering £272,000.
Other items sold recently include a selection of rather dull postcards penned by Himmler, and Goebbels's school diary. Much of this material is mundane and of limited historical value, aside perhaps from representing what Hannah Arendt dubbed "the banality of evil".
The market in items associated with high-ranking Nazi officials is in highly dubious taste, as is the sale of real or replica SS uniforms for "fancy dress". But other items that can be bought freely are nothing short of appalling, from yellow stars designed to identify and humiliate Jews, to arm-bands worn by gay people imprisoned in the camps, or identity papers and uniforms from Auschwitz.
