You can purchase a copy of this famous graph from Edward Tufte and Graphics Press. I purchased a copy for myself several years ago and am very pleased with it; therefore, I'm passing this information along to the rest of you as a public service. I assure you, there is nothing in this for me except the knowledge that I am assisting the rest of you to obtain this very desirable item.
There are two versions of the graph. The first is the original graph, in French, which measures 22 X 15 inches and costs $14 plus shipping. The second is the French graph with an English translation graph below it, which measures 20 X 22 inches and costs $18 plus shipping. Both are printed on heavy antique white matte stock in two colors -- black and brown. The photo image shown above was taken with a hand-held digital camera and does not do justice to the actual print -- the gray background is actually a very attractive antique white.
If you have never heard of Minard's graph, or if you have but are not very familiar with it, please click here to see a large version of this graph that I made from another source.
