This is just a bunch of drawings of different parts of bicycles from their inception, roughly 1877, to 1959.
From 1877 to around 1877 the drawings are more full bicycles, some advertisements, and catalog pages. Then the next page is 1924 on which there is only a drive side crank and chainweel, which is followed on the next page with 1935 (fender cross sections), 1894 (tire and rim cross sections), 1907 (gears), 1907 (crank arms), 1922-1912 (wood rim cross sections), and continues as such until page 69 where there is a full page reproduction of a poster "le petite Bicycliste".
Post that "le petite Bicycliste" poster page the years run pretty consecutive starting at 1946 and appear to be grouped by manufacturer, but it is hard to tell because there is almost no words on any of the pages, until the last few pages - around 1955 - where some captions appear.
What there is are lots of line drawings of specific sections of various bicycles, mostly: headtube setups, various lugs, drivechain setups, fenders, handlebars, generator setups, rear deraileurs, front derailuers (mostly rod controlled), wheel hubs, bottom bracket shells and hangers, etc...
If you want to see a bunch of drawings about how a specific section of a bicycle could have looked in a specific year and get a bunch of different manufacturer designs (even though for the most part you won't be able to know which manufacturer they are from) then this is a great resource.
If you just want to spend a few minutes looking at older bicycle designs to see how they relate to modern ones (like how a threadless headset was offered in 1947 - page 77) then this is also a good resource. The opening blurb on the dust jacket flap sums this up: “The 1935 prototype of what’s offered today as the hottest new derailleur design, 100-year old suspension forks, an automatic gear system from 1924, hydraulic brakes from the 1950s. They’re all here in the The Data Book.”
