Innovative: The artists use material such as human fat tissue and corpses to make their sculptures stand outTo illustrate her fall from grace, the woman also sports featherless wings on her back.

The artists created the piece using silica gel, fiberglass, stainless steel and woven mesh.

However, these materials are pretty tame for the pair.

They have been known to use human fat tissue, live animals and baby cadavers in order to challenge perceptions about death and the human condition.

In a statement on their website, they explained: 'The angel, a transcendent being, has become powerless, unable to carry out God's will, or to help those who believe in its existence.' 

One of the duo's previous works, titled 'Old Persons Home', also focused on the older generation.

The installation, created in 2007, was made up of sculptures of geriatric old men, which looked suspiciously like world leaders.

Rather than being a static piece, the models were placed in electric wheelchairs and left to bump into each other at random.

Both 'Angel' and 'Old Persons Home' have also been displayed at the Saatchi Gallery in London.
