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.
