"Pen to Paper: Artists Handwritten Letters, from the Smithsonian's Archives of American Art," edited with an introduction by Mary Savig.
Reproductions of letters are included, along with brief biographical info about the artists, analysis of the handwriting and how it reflects that individual's approach to art, and other interesting bits. (Full typed transcriptions of the handwritten letters are also included at the back of the book.)
I borrowed the book from the library. Hardcopies and a Kindle edition are available at:
