OEUVRES DU PHILOSOPHE DE SANS - SOUCI PREMIERE et SECONDE PARTIE NOUVELLE EDITION (trois parties en deux). CHEZ J. H. SCHNEIDER, BERLIN ET SE TROVE A AMSTERDAM (1764 & 1785 supposedly on the second). 
 
Matching set, apparently 1764 and 1785 (?) according to the title page. Semi-stiff gray/green plain paper boards. Partial cursive spine title still present on the first part, and the title is missing on the second volume. Apparent corner chew (chip) to pp. 145 to 166 on vol. 1. Clean rippled pages with nice clean pages and just a hint of scattered foxing. Vol. 1 has some small stain marks to the front board (a few tiny ones to the rear), and there are a few small stain marks to the rear board of vol. 2. From the last part contents, it appears to contain the third part as well. The spines on both have some paper wear and the covers are lightly rubbed. The two volumes measure about 7 x 4 1/4. Illustrated. In French. March 1760 date at the front section (two pages after the title page). Rare!
