Mexican artist, Filemon Trevino, has accomplished his lifelong dream of entering the Guinness Book of World Records by creating the world’s largest work of art.

Trevino presented a Guinness certificate declaring his quarter-mile-long pencil drawing as the world's largest. The artist, who hails from Monterrey in Mexico, 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 even 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. "I forgot to drink water," he said. "I didn't know anything about friends, my family or anything else in the world. I started to grow a beard and lost (35 pounds) 16 kilograms."

Trevino started the drawing in July 2004 and completed it in August 2005. He was not able to apply for the world record until he found someone willing to display the work and sponsor Guinness' $600 entry fee. The work was unveiled in March at the Regiomontana University.
