Welcome back to the fifth instalment as we take a decade by decade look at the history of the LEGO Group, before they celebrate their 90th Anniversary on August 10, 2022. Last time, we left the 1960s behind: wheels and trains have entered the mix, and DUPLO is helping little people to build big things. Today, we move further into the ‘70s: an era where characters enter the mix, more realistic models are possible, and a new CEO enters the mix.
