Bomb hugger which depicts a young girl hugging a bomb tight to her chest was first created by Banksy in 2003 and appeared on a wall in the East End of London.

One of Banksy's most haunting works is Napalm Girl, which he created a year after Bomb Hugger. It features a reproduction of one of the 20th century's most recognisable images of war. The photograph of Vietnamese-Canadian Phan Thị Kim Phúc OOnt was captured in Trang Bang by photographer Nick Ut in 1972. The nine year old can be seen running naked through the street suffering with burns from a napalm attack.

Banksy's recreation depicts Phan Thị Kim Phúc OOnt running between Ronald McDonald and Mickey Mouse.

In 2004, Ice Cream Bomb appeared on a wall at Brighton Beach. Another iconic Banksy work which depicts children and the loss of childhood is Girl with Balloon, 2004, a simplistic work which leaves the viewer wondering what the balloon represents and whether the child has released it or she is grabbing for it. In 2014, an original of Girl with Balloon was removed from the wall of an east London shop and sold. In 2007, a version was sold at Bonhams and in 2012, another sold for $103 883 (£73 250.)

Another recurring motif in Banksy's work is the police, or ''coppers'' to use the British slang. Banksy's Kissing Coppers appeared on the wall of a Brighton pub in 2004. The placement was no accident, Brighton is known the world over for being one of the foremost gay-friendly cities. The work was removed from the pub wall in 2014 after several attempts by thieves to remove it. The pub owner sold it to a private buyer in Miami for an unknown figure, rumor has it, it was for around half a million dollars.

Banksy's Snorting Copper appeared from 2005 in several places around London, including behind Waterloo Station (on Leake Street) and in Shoreditch, on Curtain Road. The piece was quickly removed from public view.

The introduction of the UK police's 'stop and search' policy on young people in the mid 2000's sparked many a debate around human rights' issues. Policeman Searching Girl appeared in Glastonbury in 2007.

It's no secret that Banksy works sell well at galleries and in the sale room. A signed version of Toxic Mary dated 2003 and numbered 33/150 sold at Bonhams in September 2011 for $6 725 (£4 750) inc. premium. Search realized prices for Banksy on Barnebys here.


Now to across the Channel, to the master of pixels, Invader. Invader is most recognized for his pixellation tiles, inspired by the 8-bit video games of the 1970's and 1980's, with his name deriving from the popular arcade game Space Invaders.

The artist, although he works incognito, is known for his sense of humour. Although he studied at the École des Beaux-Arts, he claims he went to a tiling school on Mars.

He began his 'invasions' in his home town in 1998, and since then he has gone on to 'invade' 33 cities across 65 countries including New York, Los Angeles, Hong Kong, London and Manchester.

Invader gives his fans many platforms to enjoy and discover his work on, including published books and maps, as well as QR codes and an app for fans to ''collect'' and compete for how many of his works they have spotted.

However, he does not count the authorities as his fans, as in 2010, Invader was arrested for putting a mosaic on the Hollywood sign.

The highest price ever paid for an Invader work was at Christie's, Hong Kong, in 2015 for $351 000 (2 680 000 HKD) more than double its low estimate. Search realized prices for Invader on Barnebys here.
