If you have ever seen this book "Horatio Barber - Aerobatics" on Amazon or other online stores, it's a book right from 1918 (!), which is actually available for free, at this address:
I made a PDF version optimized for printing, with all white pages removed, white margins reduced and with 2 original pages placed on a single page, in landscape format. Text and "plates" (images) are separated. Total number of pages: 45, therefore you can "save the woods" and print the whole book on just 23 sheets of A4 paper.
