The Official aviation guide of the airways
The Official Aviation Guide of the Airways is a 1929 timetable periodical issued by the Official Aviation Guide Company of Chicago for air travelers and airline staff, listing routes, schedules and fares across American carriers. The pages show dense tabular timetables with route tables, fare boxes and company headers, plus a system map of airline routes across the Midwest that a designer could use for typographic grids, tabular layouts and vintage route-map styling.
