Published in deliveries, this suite is sometimes accompanied by a prospectus engraved in lieu of title, and which describes the prints There are at least three successive versions of this ad we consulted;. first described the first sixteen prints, the second most mentions a "Supplement forming prints 4", and the third describes the entire book consists of 24 prints Nowhere is the issue of quality of the paper used in these prints, and. all the "big" examples we reviewed are printed on Auvergne paper, certainly large but poor bill. This paper from the mills Dupuy is typical of French paper large format whose quality declines at the end of the eighteenth century, supplanted by productions in Holland and Italy. However, we find in the margin of one of these flyers, an ad for a new production Helman, memorable facts of China's emperors, whose first delivery is scheduled for April 15, 1788. On size smaller than the Suite Conquest (either in-4), the memorable facts are available on the same large paper Auvergne, but also "the whole work painted in watercolor on paper of Holland."

The binding is not signed, but a bill of similarity is observed and similar chains on binders bearing his label collection Mortimer L. Schiff: a 1790 Telemachus; 2 and 1787 medical books (S. Ricci, French signed binding in the Mortimer L. Schiff collection, II, New York, 1935, No. 140 and 142). Similarly, R. Devauchelle assigns a binding whose decoration includes a frieze of stars comparable to that provided on the dishes of our copy (R. Devauchelle, Bookbinding, historical research ... Paris, 1995). This date "to 1792-1795.". Our copy has, on paper of the lower guard, a watermark dated 1792; This binding can be logically dated in the same range of 1792 to 1795. Its dimensions are approximately 38.5 x 27 cm.
