"Unbelievable Time Required To Cover Immense Distances of Space", presumably drawn around 1918 based on the time-periods described in the margins. Travel-time to various astronomical points was calculated based on the immense speed of "two miles per minute", or around 120 miles per hour; actual escape velocity is seven miles per second, although the steam-powered air-ships pictured could certainly break the bounds of gravity if given enough time. From Our Wonder World.
