COYER (Gabriel François, Abbé). Development and Defense of the System of the Commercial Nobility. Printed in Amsterdam and available in Paris, Duchesne, 1757. 2 parts in 1 vol., in-12 format, glazed calfskin, smooth spine with decoration, title label, triple gilt fillet framing the covers, gilt edges (contemporary binding). A defense of the famous work *La Noblesse commerçante*, published the previous year. Associated with the group of economists, Abbé Coyer (1707–1782) caused a scandal by arguing that the nobility should engage in commerce, pursue personal enrichment, and thereby make themselves useful to the public. A very lively controversy ensued. Engraved bookplate by Bernard Roy.
