This 1922 record from the NASA Technical Reports Server is a government technical report on early European commercial aviation, with no stated author or title, prepared for engineers and aviation researchers. Its four pictures are plain black-and-white line charts and a route map: three graphs track departures, arrivals, flight numbers and passengers on airline routes from 1919 to 1921, and the map shows fixed, intermittent and projected air routes across Europe and North Africa. A designer could draw on the simple grid-and-line chart styling and the dotted route map for clean infographic treatments of early aviation data.
