Early 1800's France... Printing presses were very common and flyers and placards were being produced en masse.

Also, working at a flour mill, as I do... If you want the best, purest flour, you get it from the head (start of) the milling process before flakes of wheat bran (the skin of the wheat kernel) can get ground up and mixed with the pure, white flour.
Head of the mill flour is more expensive and aesthetically pleasing but not always necessary.
If you are making breading or pretzels, you are not worried about color or rise, so you buy flour that runs the whole process of the mill. "Run of the mill" flour.
Run of the mill... Average, commonplace
