Here’s one for @airlinemaps: a wonderful infographic/diagram mashup from the 1950s that packs in heaps of information, right down to the type of airplane used on each route (denoted by the colour of each line). Flight numbers, time of departure/arrival, days of service, through routing of flights… it’s all incorporated into the one graphic. And it’s trilingual as well!

Compare with this very similar diagram of Polish Airlines LOT routes from 1939 (June 2015, 5 stars).
