Looking for a Digital Copy of Any Handwritten Sermon of St. John Vianney

I am looking for a digital copy of any personally handwritten sermon of St. John Vianney. From what I have read, I am under the impression that 80 or so are extant, but I have not been able to locate any. There should be at least one available, as part of it has been placed on the cover of the following book: QUESTION: Does anyone know where I might find a (preferably) digital version of at least one full-length sermon of St. John Vianney? Or, at least a paper version of it? Thank you. REASON FOR THE REQUEST: If I can locate at least one of his full-length handwritten sermons, I could then explore the possibility of producing some gylphs in order to produce a "Curé of Ars" font for typography purposes.
