Jack Brait from Marshfield, Massachusetts, completed at a breakneck speed what's been billed the world's largest jigsaw puzzle.
“I started with the Jungle Book section right here and this took me 10 days and 68 hours," the 20-year-old said of putting together the 40,320-piece "Memorable Disney Moments" puzzle.
Brait finished the entire thing in about 423 hours, equating to a little less than 18 days of puzzle work spread out over time to make the 6.5-foot by 22.5-foot puzzle.

He timed it all on his iPhone as he completed section by section.
Brait can tell you off the top of his head how long each Disney section of the puzzle took him.
His proud parents say he was diagnosed with a high-functioning form of autism just before his third birthday. Brait's form of autism allows him a hyper-focus on things like puzzles. It's a talent he is very proud of.
This isn’t the only monster puzzle Brait has tackled. He completed a more than 32,000-piece behemoth back in 2014 and then donated it to his middle school in Marshfield.
The company that makes the Disney puzzle, Ravensberger, posted that it should take someone about 600 hours to put it all together.
Brait, who wants a bigger puzzle challenge, has a message for Ravensberger: “Bring it on.”
He would like his next new puzzle challenge to be anywhere from 50,000 pieces or more.
