LEGO 1965 / Classic / Building Sets

The LEGO Classic Building theme from the 1960s consisted of sets that focused on general construction and architectural design using standard LEGO bricks. Unlike specialized themes, the Classic Building sets from this era emphasized foundational building techniques and allowed for the creation of various structures and designs. It represented one of LEGO's early efforts to promote versatile brick-based construction.

1965 LEGO Sets

1965 was a growth year for LEGO. The number of people employed by LEGO at Billund reached 600. LEGO was also increasing the pace of new development. Continued sales growth for the company also meant continued expansion of its manufacturing capacity. They also developed several new elements specifically for the North American market. Beginning this year, the primary illustration on each set's box would show only models that could be built with that set's contents. Previous sets featured generic models not necessarily possible.
