2pp., 8vo. On bifolium. In fair condition, on aged and worn paper. Written in a difficult hand. Dated 'M<?> 7 Fevr 69'. Addressed to 'Monsieur & Mes colleguès'. He writes regarding the 'Commission de la Bibliothèque', and their direction that he send copies of their prospectus to 'M le <?> Hofman à Berlin', with reference to 'Mr B'. The sepia portrait photograph of d'Aubigné is 9 x 5.5 cm and appears to have been cut down, but is otherwise in good condition. It is a head-and-shoulders studio shot, showing the historian in wing-collar shirt staring to the left from under his bushy eyebrows. An engraving of the image was made, and is widely-known, but other copies of the original photograph have not been traced.
