Telstar Logistics: "Flight thru Instruments" and the Fine Art of Instructional Illustration: "Published as a pilot-training manual by the US Navy in 1945, 'Flight thru Instruments' teaches proper aeronautical navigation techniques through the use of elaborate illustrations -- the kind of stuff that today might be called 'info-graphics.'
But oh, what info-graphics these are! Produced entirely by hand, the illustrations in 'Flight thru Instruments' possess a richness and accuracy of detail that -- if we may say so -- puts the majority of today's graphic artists to shame."
These are totally awesome graphics. We need more like this today.
