About LEGO Hobby Set
The Hobby Sets theme was an effort by LEGO to capture the attention of hobby shop buyers in the mid 1970s. Each of the Hobby Shop sets included enough pieces to build a miniture replica of each set. The initial run of the theme included 8 sets between 1975 and 1978 with one last set released in 2003. The first wave in 1975 was based on iconic cars, while the 1976 line included a train and two motorcycles including one past car.
1978 LEGO Sets
1978 was transformative: the modern minifigure arrived with articulated limbs and standardized proportions, becoming the heart of LEGO play. Three pillars launched in force—Town, Space, and Castle—bringing buses and services to city streets, astronauts and bases to the cosmos, and knights and keeps to medieval scenes.
