A signed autograph letter by Pierre-Joseph Redouté, acknowledging his reciept of 30 francs from "Monsieur Debure libraire" for the 30th and final part of Les Roses, Redouté's most famous work, which was published in installments between 1817 and 1824. This must be the Paris bookseller Jean-Jacques Debure (1765-1853) or his younger brother Marie-Jacques Debure (1767-1847), who were "libraires du Roi et de la Bibliotheque du Roi" from 1821 to 1830. The book was printed and published by Firmin Didot. Oddly, an addition by a different hand below left notes "payé le 26 fevrier" (paid 26 February). Perhaps Redouté is writing to Firmin Didot and he was to reimburse Debure for this expense. It in any case suggests that Debure is not merely buying copies of the book to sell but was involved in the publication of Redouté's Les Roses in some manner.
In fine condition, with only a small piece of paper stuck to the top right corner, not approaching the text.
