Marx by Corrine Maier is a graphic novel format biography of Karl Marx. Marx's Communist Manifesto is something I had to read in 9th and 10th grades, so having a graphic novel biography aimed at that age range makes sense to me.
Maier's biography, told in the first person with Marx at various ages walking the reader through his life, along with scenes where Marx is actually living his life, serve to give the background on what lead Marx to write his most famous work. It also tries to give insight into his career as a revolutionary against capitalism as it stood at the pinnacle of the Industrial Revolution.
Many other philosophers and revolutionaries make cameos in this book. Unfortunately, as seems to be the case for graphic novels, there isn't much information given on these others. It seems to be left to the reader to either already know their stories or to look them up later.
