What you see here is a self portrait of the artist Marc Quinn, an incredibly lifelike and detailed cast, that he made out of his own frozen blood.
Marc has been making these portraits every five years since 1991, so it would be interesting to see them all together, progressing in age over the last twenty years.
Each piece takes over four liters of blood to construct, which is gathered over a five month period. These frozen bloody heads would make the ultimate centerpiece for the Monster's Ball!
