Children’s Birthday Party, a 1000-piece jigsaw puzzle by Jan van Haasteren promises a delightful and humorous experience. The assembled image transports enthusiasts to a lively birthday celebration where children are full of energy, presents are being playfully tossed around, and even the animals from the petting zoo are gleefully joining the festivities.

Jan's distinctive humor is embedded in the smallest intricacies of the puzzle, encouraging puzzlers to examine each detail closely. While many fans will eagerly seek out Jan's trademark—the shark's fin, a staple in every puzzle—they can also enjoy spotting his other favorites, such as Saint Nicholas, The Hands, The Dentures, and even a self-portrait of Jan, cleverly incorporated into nearly all of his puzzles.
