Nearly a year after Cra-Z-Art and Kodak first revealed plans to produce the world’s largest commercially available puzzle, a couple in Pennsylvania actually completed it.

Jim and Helen Kernen of North Wales, Pennsylvania completed the 51,300-piece puzzle — the combined form of 27 smaller puzzles, each containing 1,900 pieces. Cra-Z-Art Chairman Lawrence Rosen used National Puzzle Day to share the news that the couple has the first verified completed puzzle in the U.S.

“Cra-Z-Art is very excited to recognize Jim and Helen for accomplishing this impressive feat and to know that they’ve put together a one-of-a-kind, record-breaking size puzzle of beautiful imagery from around the globe. Though it can be challenging to complete, puzzling is a great, fun activity that can be done individually or with the whole family,” Rosen says.

The puzzle is available to purchase online through Walmart, Amazon, and Hammacher Schlemmer.
