Going back a few days, to Slovenia: at my stop in Maribor I couldn't resist buying this pamphlet, spotted in a local antiquarian book shop (€7). It's from the early 1960s and the cover, roughly translated, says "Cyclist! You're not the only one on the road!" It gives basic tuition on how to behave on two wheels and strikes a quaintly patronising tone, from the time when bikes were seen more as a nuisance than a positive (they still are in many places, of course). It also has a gruesome illustrated section on dealing with the injuries caused by accidents with cars, which seems to me more to the point.
