C'est ce que je cherche, [...] et j'ai communiqué mon idée à Perrin, qui m'approuve et m'encourage. Si vous aviez ce que je demande, ce serait une bonne affaire, et nous aurions une jolie petite pochade qui serait jouée longtemps [...]". The person named Perrin is likely to be the artist and theater director Émile Perrin who directed the Opéra-Comique from 1848-1857 and later briefly the Paris Opéra. Vanderburch (1794-1862) was a successful and prolific playwright but no collaborations between Boïeldieu and Vanderburch are recorded. Boïeldieu did indeed collaborate with Jules-Henri Vernoy de Saint-Georges (1799-1875) in the early 1840ies. Saint-Georges is best known as the librettist of Donizetti's "La fille du régiment", Bizet's "La jolie fille de Perth", and his numerous co-authorships with Eugène Scribe. - On stationery with embossed monogram.
