Dutch supermarket giant Albert Heijn devised an inventive and original advertising campaign,
which involved thousands of school children building small jigsaws.
These were then assembled into one huge jigsaw in an Amsterdam stadium.
The final image comprised photos of all the players from every top-flight Dutch soccer team.
Given it was assembled all over the country, the mosaic needed to be segmented, printed,
and cut, and marked up so the stadium crew could be sure it was going back together properly!
