Minard / Morse / Tufte and Authenticity on the Web (2018)

But there are more similarities between the lower two images, which separates them from the original:

While there is more evidence, it may be safely concluded, that the two lower versions, the one found in Edward Tufte’s publications and the one found on Wikipedia, are the same, but are not the same as the image provided by the Bibliothèque numérique patrimoniale des ponts et chaussées . Based on contextual evidence, citations, and assessment of the images, we may conclude: The Wikipedia file is a copy of the version found in Tufte’s “The Visual Display of Quantitative Information” (probably the 2nd edition as of August 2007), scanned from The Economist’s Christmas Special of 22 December 2007. And, as it seems, the image found in Tufte’s book is a redrawing by Elaine Morse after the authentic print copy in Folio 10975 of the École nationale des ponts et chaussées, Paris.
