Frieze London, the contemporary art fair, is currently displaying a wide array of paintings and photographs. Among the works is a two-metre-tall inkjet print by Wolfgang Tillmans, titled 'Paul, nude, golf ball', which dates from 1994.
Meanwhile, Frieze Masters, located on the other side of Regent's Park, presents a different collection, including a 16th-century painting by a follower of Hieronymus Bosch. The Masters fair also features works by established modern artists, some of whom are deceased, such as Cy Twombly and Leon Kossoff.
A notable item at Frieze Masters is a triple-horned, fossilised Triceratops skull, estimated to be 68 million years old. Palaeontologists have reportedly expressed concerns that the demand for dinosaur specimens among the ultra-rich is driving up prices and limiting museum acquisitions.
Other items available at Frieze Masters include armour, silverware, Arabian carpets, and 19th-century nudes. The fair also displays artefacts such as a manuscript page, a face mask from an ancient Egyptian coffin, and a stone head of a priest from 2nd century AD Palmyra.
