Board game and toy company Ravensburger have unveiled a unique, commemorative puzzle celebrating Mickey Mouse’s 90th anniversary. The one-of-a-kind puzzle is called Mickey Through the Years, and features nine decades of hand-drawn images and photos over 40,320 puzzle pieces.

The puzzle box weighs over 50 pounds and retails for $600. Once fully assembled, it’s over 22 feet long and 6 feet high, making it the largest Mickey puzzle in the world. As evidenced by its size and cost, this puzzle is not for the faint of heart. It’s estimated to take approximately 600 hours to fully assemble.

It ties the largest non-Mickey puzzle in the world, which also happens to be a Disney-themed puzzle designed by Ravensburger.

“Over 40,000 puzzle pieces celebrate Disney’s most iconic character in Mickey Through the Years,” said Thomas Kaeppeler, President of Ravensburger North America. ͞”We worked with Disney’s designers and artists to create a challenging puzzle and one that is equal parts art to keep the most persistent puzzlers going as they complete each image of cherished scrapbook memorabilia throughout Mickey’s amazing 90-year history.”

The puzzle is made up of 10 different quadrants of 4,032 pieces each. Each quadrant depicts a different decade in Mickey’s history, beginning with his first appearance in Steamboat Willie in 1928. Examples include The Mickey Mouse Club in the 1950s, and Mickey’s Christmas Carol in the 1980s. The final quadrant is a unique sketch that celebrates Mickey’s 90th anniversary, along with friends Minnie Mouse, Pluto, Goofy, Donald, and Daisy.

The official celebration of Mickey’s 90th anniversary takes place November 18. The Mickey Through the Years puzzle is available to purchase via Amazon, Disney, Ravensburger, and select hobby stores today. It has a suggested age of 14+.
