"The Tube Train" by Cyril E. Power is a color linocut from 1834 that is one of a series in the show that deal with the London Underground. I love the comic quality of the image, as well as the sense that you're going round a curve. One of the least abstract in the exhibit, I do think that this print gets at the kind abstracted humanity that riding public transport seems to engender.
Though the majority of these prints concern themselves with war machines, zooming cars and whirling pleasure machines, I loved Lill Tschudi's examination of where all that power comes from. Here "Fixing the Wires" gives us that same jazzy brand of abstraction applied not so much to vehicles as to infrastructure.
