In 2012, the United Nations Office on Drugs and Crime (UNODC) visited different areas of Colombia to educate children and young adults on how to recognise, report and prevent human trafficking. As part of this program, children from various schools and communities created murals to show their understanding of human trafficking and their support of modern slavery survivors. Of the 1,900 children with whom UNODC worked, the majority lived in areas where levels of prostitution and drug crimes are very high. This mural is one of two created in Medellin, which is the second largest city in Colombia and the capital of the region of Antioquia. It shows white silhouettes of people with barcodes across their bodies. The red banner reads on sale/for sale in Spanish, Italian, German and English: 'en venta...in vendita...zu verkaufen...for sale...en venta'. These phrases are repeated on the left-hand side around the woman who faces away from the viewer, with her hands clasped around her knees.
