Filemon Trevino accomplished his lifelong dream of entering the Guinness Book of World Records thanks to a quarter-mile-long pencil drawing now certified as the world’s largest. The Mexican artist said he spent 6,000 hours and used 800 pencils to complete his representation of the heart and circulatory system, with symbols including doves, geometric shapes and hundreds of yards of intertwined tubes. Breaking the record became an obsession that led him to neglect his health: he was hospitalized seven times for dehydration, heart and kidney problems and fainting spells, all attributed to long hours spent drawing in a hot, stuffy room. Filemon Trevino started the drawing in July 2004 and completed it in August 2005 but he could not apply for the world record until he found someone willing to display the work and sponsor Guinness’ $600 entry fee. Update:This student claims he created the world’s biggest drawing! Thanks to ‘Darrin’ for the link.
