‘Gangsta Rat’ depicts a black and white rat wearing a New York Mets baseball cap, a chain necklace, and carrying a ghetto blaster. The character is an adaptation from a mural created in 2002 and is reminiscent of the New York underground style that was prevalent across the UK in the 1980s and 90s. The rat also appears to have tagged “iPow” on the wall behind him in spray paint. The image is an ironic social commentary on the ubiquity of Apple products, and POW is a clear reference to Banksy’s print publisher: Pictures on Walls.

Banksy initially released Gangsta Rat in the red colourway as an edition of 150, then later Gangsta Rat was produced in 6 rare colour-ways including blue, pink, green, grey, orange and mint. Banksy's appreciation for rats is often attributed to French stencil artist Blek le Rat, who is regarded as the ‘father of stencil graffiti’ and initiated urban art in France in the 1980s.

In 2023, an edition of Gangsta Rat sold for an impressive £114,300 at Sotheby’s Auction House as part of their solo Banksy sale.
