The Physical Impossibility of Death in the Mind of Someone Living

Damien Hirst's famous pickled shark, a mixed media piece (tiger shark, glass, steel, 5% formaldehyde solution, 213 x 518 x 213cm according to the catalogue to the 'Sensation' show that it first appeared in).

The artwork is currently on its second shark, after the first one decayed and made the fluid it floated in go all cloudy. Despite being a remake it still sold for $8,000,000 in 2004.
