A very basic and rather incomplete definition of steampunk is: 1.
a subgenre of science fiction and fantasy featuring advanced machines and other technology based on steam power of the 19th century and taking place in a recognizable historical period or a fantasy world.
2.
a subculture inspired by this literary and film subgenre: the fashions and gadgets of steampunk.
This extraordinary steampunk Vespa scooter dubbed Guardian and created by Greek sculpter/designer Chris Cofitis, in our humble opinion deserves a spot in the Vespa collection at the Piaggio Musuem at Pontedera, right next to the Guido Ricci Masè Vespa.
