The LEGO store gave this out to us VIPs as a gift after spending a certain amount, I can’t remember how much. This set which creates a model of the core 2 x 4 brick (it doesn’t work like one though) celebrates the construction toy’s 60th birthday!
A coworker recently borrowed the instructions. Hunted down all the equivalent parts via Brick Link (or LEGO.com?). Then built his own version of this in blue. Pretty funny and impressive.
Given how LEGO is now the number one toy company in the world after almost going under in the Aughts, I hope the iconic brick carries on to be 100!
