Reçu autographe signé de Gérard de Nerval

Autograph receipt signed "Gérard": "J'ai reçu de M. Rouy la somme de 10F à compte. Gérard. Ce 27" ["I have received from M. Rouy the sum of 10F on account. Gérard. This 27th"]. Daniel Rouy was manager and cashier of the newspaper La Presse.
Two transverse crease marks.
This acknowledgment of debt, simply dated "ce 7" ["this 7th"] could have been written in August 1849, if one refers to a letter to Ernesta Grisi, companion of his friend Théophile Gautier, in which the poet mentions such a debt: "Je n'ai pu toucher l'argent qu'aujourd'hui mercredi. M. Rouy n'y était pas. J'y suis allé 4 fois aujourd'hui..." ["I was only able to collect the money today Wednesday. M. Rouy was not there. I went there 4 times today..."] (Pléiade, volume 1, letter 143 of August 30, 1849).
However Michel Brix, author of Nerval, Glanes et miettes de presse and member of the Royal Academy of French Language and Literature of Belgium, has very kindly pointed out to us that Nerval signed "Gérard" rather between 1837 and 1840 and that in 1849, he signed this kind of note "Gérard de Nerval".
