“It’s cold and wet. What can be done? / A trip on the subway, just for fun!” A father and his two children run down into the New York subway to ride the rails and explore the trains all day long. Every line is represented as the family hops from track to track. Set on stark, black backgrounds with free-flowing brush strokes, the trains swoop and turn on ribbons of appropriately colored paths. And when many of the lines converge in the middle of the book, aptly at Times Square, they tangle like spaghetti strings. After a full day of fun, the children climb out, ready for subway dreams at night. In a witty visual twist, the humans appear as traffic-sign–style white pictograms, with round heads floating over stick bodies (and occasionally attired to suit the text). Inspired by Niemann’s clever New York Times blog, “Abstract City,” this artistic tour de force will appeal to New Yorkers and visitors alike. Eagle-eyed enthusiasts will carefully plot every stop, spotting subway humor along the way. That the meter occasionally strains is the only false step on this fresh, striking subway tour.
