In the city of New York the summer of 1899 was signalized by the dismantling of the Elevated Railroads. The summer of 1900 will live in the memories of New York people for many a cycle; the Dodge Statue was removed in that year. In the following winter began that agitation for the repeal of the laws prohibiting suicide which bore its final fruit in the month of April, 1920, when the first Government Lethal Chamber was opened on Washington Square.
— Robert W. Chambers, The King In Yellow
So I started reading The King In Yellow and so far it’s basically Futurama if it was written in 1895 about the far-off future of 1920.
