Jeff Koons artwork made from Sean Penn's guns sells for $1.4 million at charity auction

A Jeff Koons artwork created from Sean Penn's personal firearms collection sold for $1.4 million at a Beverly Hills charity auction. The piece was purchased by CNN anchor Anderson Cooper. Proceeds from the sale benefit Penn's J/P Haitian Relief Organisation. Charlize Theron reportedly encouraged Penn to donate his guns for the artistic transformation. The auction took place in January 2014. Koons's involvement adds significant market value to the conceptual work. The event highlights the intersection of celebrity, philanthropy, and contemporary art collecting.
