One of the most enigmatic images of Banksy’s famously provocative oeuvre, the iconic image of an ominously masked and hooded young man walking Keith Haring’s cartoon dog with a metal chain is both a political commentary on the rising violence among youth in England and an ode to the power of street art as a means of resistance. Banksy's Choose Your Weapon will be offered as a highlight of Sotheby's upcoming The Now Evening Auction.
