Pseudonym of Gaspard-Felix Tournachon (1820–1910), a French photographer, caricaturist, journalist, novelist, and balloonist. ALS in French, signed "Nadar," three pages on two adjoining sheets, 5.25 x 8.25, Nadar Photgraphie Artistique letterhead, 1858. Letter to his friend Boule, on whose name he plays, making ornithological citations from Linnaeus and Buffon. In part (translated): "I'm told you're not altogether happy about the bill my cashier (!!!) sent you, and you want me to intervene personally...I persist in clinging to the happy system of limited shareholders I have created whose interests are represented by a 311' party. This allows me to have nothing to do with administrative questions, the mere thought of which makes me yawn wide was never any good at math...If you hadn't run off like a rabbit yesterday with the speed of the bird whose name you bear...I would have informed you, my dear lamb...that I intervened just sufficiently to smooth over the fearsome slopes of our current prices...you should be treated with all consideration...our maximum discount...I still have a few leaves left from my 'Pantheon' reserved for my friends which makes it your duty to have one for yourself Paf, that's you (a friend)!" In very good condition, with uniform light toning, several pencil notations, some mild soiling, and paper loss to second page affecting a few words of text.
