As part of a very well coordinated campaign to underpin their relationship with the top division of Dutch football, supermarket giant Albert Heijn commissioned a jigsaw. Not any old jigsaw though!

This one features 4,800 pictures of top-flight footballers, each footballer comprising 252 jigsaw pieces, and all those images together built up the image you see below.

The overall image depicts legends of Dutch soccer through the years, and it presented us with some very interesting challenges.

Once built, the mosaic had to be delivered for printing with the 4,800 images arranged in groups of 16, precisely spaced by fixed margins for the cutters, and also visibly numbered according to a scheme that would allow the pieces to be assembled in locations all over Amsterdam before being re-united in the Olympic Stadium!

For the Big Picture project in Birmingham, sunshine was a problem. As you can see, it was less of an issue in Amsterdam...
