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.
1975 LEGO Sets
1975 expanded Basic Building Sets and introduced more systematic, idea-led boxes. Proto-minifigures—small, faceless figures with single-piece legs—appeared in town and train sets, foreshadowing the 1978 minifigure. LEGOLAND-branded sets emphasized construction vehicles and realistic machinery, reinforcing everyday play before the arrival of dedicated Space and Castle themes.
