I believe this photo was taken in 2015? The Glendale Galleria had this pop-up called the LEGO Americana Road Show where they would go around to different malls to display replica of iconic American buildings.
This qualifies as public art because it was free to get in and it’s at a highly accessible location. I wish I had more photos of these LEGO displays from that day because unfortunately this large scale LEGO model of the Capitol building is all I could find :-/.
I am always impressed with what one can do with LEGOS. I’m always tempted to buy the LEGO Architecture sets whenever I pass by a box. I tell myself “think of it as a 3D puzzle.” But will I ever finish one?
