Words cannot express just how much I love this cleverly thought of, deftly executed and incredibly cute rendering of Paris’ RER Line B as the Eiffel Tower. Hagiwara has drawn her inspiration from the official RER line diagram, with the bifurcation of the line becoming the “legs” of the tower. Almost seems like a clever advertisement for the RER, and only took her 20 minutes to execute!
