The Pop Up Book continues a tradition of the LEGO Ideas theme selecting projects that may otherwise not make into the LEGO range, following sets such as 21301 Birds and 21313 Ship in a Bottle. The original concept is a collaborative project by Jason Allemann and Grant Davis.

Jason’s name may be familiar to LEGO Ideas fans as one of his previous projects was successful and saw release as an official set – 21305 Maze.

The LEGO Ideas team recently announced that the next two approved projects are The Flintstones and the Treehouse, with both sets expected to launch next year.  LEGO Ideas 21311 Voltron is the most recent set in the theme, that celebrates ten years since its platform launched, to allow fans to get involved in the design process, this year.
