“The John Hancock Center set, designed by Adam Reed Tucker, holds a pivotal place in LEGO's history as a precursor to the official LEGO Architecture series. Created in 2007 and limited to 1,250 sets, it was not only a BrickWorld event kit but also a sort of prototype for the... More later LEGO Architecture set 21001, showcasing the John Hancock Center. This early collaboration under the Brickstructures brand, coupled with its limited release, underscores its significance in the evolution of LEGO's architectural series.”
