LEGO® for Adults, published in 2008, was the world’s first Brick Gun book and grandfather of the many Brick Gun books that followed. Due to a copyright issue, only 1050 books were printed. Every copy has its own serial number.
After some weeks it was sold out, so I put the content into a new book, Weapons for LEGO Lovers.
This book inspired a lot of people to design their own slide action crossbows.
