Le Thresor des secrets, et remedes merveilleux contre la peste...reveue & augmenté de plusieurs beaux remedes,...
Le Thresor des secrets is a 1631 medical book printed in Paris by Hervé du Mesnil, offering remedies against plague for French readers. Its pictures are only title-page typography: large roman capitals, mixed with bold and italic lines, and a rule under the imprint, which a designer could take as a model for period display lettering and hierarchy.
