I hadn't realized just how differently people with even the most visually noticeable disabilities were treated in the first half of the 20th century.
Much more recent times have seen some pretty cool content related to wheelchair sports: I remember the documentary Murderball[0] following a team of rugbymen and the manga Real[1] about basketball (by Takehiko Inoue of Slam Dunk fame - also about basketball) for example.
I was about to recommend Real, it is a gem (and does not read like most sport manga, you are following characters in their paths rather than rooting for a team in a competition).
