LEGO Minitalia was a theme produced and available only in Italy during the 1970s. It ran from 1970 to 1976. In order to comply with the complicated Italian importing laws of the time, the majority of the parts were produced in Italy and were different to LEGO parts in several ways. The plastic used was not the standard Acrylonitrile Butadiene Styrene plastic and the resulting bricks were not as bright in colour as LEGO ABS parts. There was no LEGO logo moulded on the top of studs as most bricks featured hollow studs similar to TECHNIC bricks. The hollow tubing used on the underside of regular LEGO bricks was changed to an X-shaped system. These differences only applied to the basic elements produced in Italy; more complex types of bricks, such as the towball and sockets, fence parts, and boat hulls were manufactured by LEGO themselves. In total, there were 21 Minitalia sets produced.
