Artists such as Jake and Dinos Chapman have customised AK47 assault rifles to highlight a global ceasefire movement.
The pair have equipped two tiny mannequins with the weapons for the AKA Peace exhibition being staged at London's ICA.
Famous names such as Damien Hirst, Antony Gormley and Jeremy Deller are among those who have worked with decommissioned guns to contribute to the display of works which will be auctioned next month.
The artworks have been created for Peace One Day, an annual event which pushes for a truce in armed conflicts around the world.
Among the items on display are a rifle decorated by Laila Shawa coated in plastic gems and butterflies and another by Bran Symondson which has been covered in US dollar bills.
The exhibition continues until September 30, and the items will be auctioned on October 4 by Phillips de Pury & Company.
