A retired sales manager in England has completed what is called the world's largest jigsaw puzzle, measuring 12 feet by 6 feet.

Eric Smith, 73, assembled 24,000 pieces of the puzzle within 179 days over six months. The puzzle has a picture of dolphins and boats.

Smith, who has been a jigsaw puzzle hobbyist for 30 years, removed all the furniture from his room and completed the puzzle on a special table.

"It has about 10 or 12 different puzzles inside one giant puzzle, I was really pleased to complete it, I've enjoyed spending two or three hours a night on it," Smith told the Sun.

Aside from Smith, another person in Britain reportedly finished the puzzle.
