Duplo is a range of toys for babies & toddlers created by Lego. Duplo is just like normal Lego sets but for much younger children.
Lego Duplo was created in 1969. This logo is still used until 1995.
In 2004, the logo is also redesigned with a friendlier appearance to match the Lego Quatro line.
In 2013, Lego DUPLO changed their logo, removing the TM symbol.
