This week, we are celebrating 10 years since the first release of Ninjago on an unsuspecting world. It was never expected to last as as long as it has, now becoming an evergreen theme:

“Originally, the NINJAGO theme was supposed to end after season 2 in 2012,” says Tommy Andreasen, Sr. Manager, Entertainment Development at the LEGO Group, who worked on the LEGO NINJAGO product line and show from the beginning. However, sets of the theme were still planned to be on sale throughout 2013. The continued success led to both the TV series and products continuing to the current day. “It just shows an incredible commitment from our fans that we are still going strong 10 years later,” he adds.

In this post, we will look through some of the concept art, as well as marketing artwork that has been released over the years. Some will be new, and some have been taken from the LEGO® archive, for a special exhibition at the LEGO House in Billund.

All images have been supplied by the LEGO group as part of a celebration of the 10 years of LEGO Ninjago.

Before we go any further, lets take a quick look a Ninjago Timeline:
