Jumbo Bricks was a small theme exclusively manufactured by Samsonite from 1964 to 1972. The sets contained bricks larger than the normal system bricks, much the same as today's DUPLO bricks. However, unlike DUPLO, Jumbo Bricks are not to a relative scale to standard LEGO bricks. They were marketed towards children from nursery school through to first grade. There were six sets produced for this theme.
1966 LEGO Sets
1966 marked one of LEGO’s greatest milestones with the launch of the LEGO Train system. Sold in 42 countries, the range introduced a 4.5V battery-powered system and a 12V electrified track version for advanced users. Specialized parts such as hook couplers, flanged wheels, and curved track debuted alongside sets like 113, 114, and 115, setting a new standard for mechanical play. Accessories soon followed, including a whistle-controlled motor unit. These innovations, led by LEGO Futura and the process development lab, established Trains as one of LEGO’s most enduring product lines.
