A wax model of Anne Frank has become the latest addition to Berlin's Madame Tussauds museum.

The teenage diarist has been sculpted at the age of 13 holding a pen and sitting down at a wooden desk, about to write in her famous journal. She appears to be smiling and the exhibit also features things that would have been prized possessions, including magazines, a hand-made dress and a copy of the novel Uncle Tom's Cabin.

The waxwork, sculpted by a team in London, was officially unveiled on Friday, with Thomas Heppener, the director of Berlin's Anne Frank Centre, joined at the ceremony by pupils from a nearby school named in her honour.

This month marks 67 years since Anne, then 15, died in the Bergen Belsen concentration camp. Her account of her life in hiding from the Nazis in an Amsterdam attic remains one of the most powerful and well-known personal stories of the Holocaust.

Nina Zerbe, a Madame Tussauds spokeswoman, told Germany's Spiegel that the exhibit had been developed to "paint a complete picture" of the Frank family's life. "We wanted to show Anne Frank in the context in which she lived," she said.

She added that the aim was to offer visitors a "three-dimensional history lesson", although Bild Zeitung newspaper reported that some people have criticised displaying the Holocaust victim in such a lighthearted environment.

There are 12 Madame Tussaud museums featuring waxworks of Adolf Hitler; Berlin and London. Soon after the Nazi leader was placed in the Berlin museum, a man came and decapitated the figure.
