Please help us transcribe these letters in the Smithsonian’s Archives of American Art. Your transcriptions will be featured in an forthcoming publication, “The Art of Handwriting.” In our age of e-mails, texts and tweets, when handwritten letters have ceased to be a primary mode of person-to-person communication, this book will explore what we can learn from the handwriting of artists including Georgia O’Keeffe, Isamu Noguchi, Willem de Kooning, and Thomas Eakins.
