Buenos Aires, Buenos Aires, Argentina. 20th Sep, 2015. A cap covers the pyramidal top of the Obelisco, in the center of Buenos Aires. The intervention was designed by artist Leandro Erlich to create an visual illusion, a sort of trompe l'oeil changing a landmark of the city, while at the same time placing a copy of the top in front of the MALBA (Spanish acronym for Buenos Aires Latin American Arts Museum) to commemorate its 21st anniversary. © Patricio Murphy/ZUMA Wire/Alamy Live News
