Inspired by Cildo Meireles Inserções em circuitos ideológicos 2. Projeto Cédula, Monroy inserted messages taken from demonstrations against violence from drug cartels in Mexico into the same flow of this drug’s economic system. Monroy did this by stamping bank notes with these messages. Those bills were obtained at the Benito Juarez Street black market in Culiacan, Sinaloa. These bank notes allegedly came from money laundered in that city. Monroy uses those stamped bills to buy a dose of cocaine in the USA. He reverted the money flow to insert these political messages back into this black market system.
