1975: minifigs, but not as we know them...
Today I have uploaded brand new images of sets released in 1975. The big event of the year was the introduction of minifigs, but not as we know them today: these were armless, faceless and without moving legs, but they were recognisable as mini people and of a size that made them more-or-less compatible with the LEGOLAND sets of the day. They represented doctors and nurses, policemen, firemen and even cowboys. It didn't matter at the time that they didn't fit in the vehicles (e.g. 659) or fit through the doors: it was great to have people at last.
Looking at the pictures today, it's interesting to see how LEGO represented them sitting down (detach the torso from the legs) and holding things (use a plate between their torso and legs). You can see examples of both in 363, the first hospital set, pictured here.
The bendy-armed people were still going strong, and it was a good year for trains, with the release of some really nice locos and rolling stock, and also for 'hobby sets', the forerunner to Model Team: realistic large scale models for older kids (and their fathers!)
The minifig had arrived, but it would be a full three years before they sprouted moving arms and legs, eyes and mouths to become the iconic form we know and love today.
