LEGO Brickstructures was a subtheme of Architecture that was released in 2008 and contained two of the very first sets created by Adam Reed Tucker, the Sears Tower and the John Hancock Center. Because Adam Reed Tucker was a Chicago architect the first models reflected his hometown inspiration. Both these original structures were re-released and slightly re-imaged in the Landmark Series subtheme.
