The development of the space-time view of quantum electrodynamics. Offprint. With Typed letter signed in Feynman's name by his secretary, with cover

Feynman, Richard (1918-88) (1) The development of the space-time view of quantum electrodynamics. Offprint from Physics Today 19 (1966). [11]pp. Light creasing. (2) Typed letter to Eliane Jobredeaux on California Institute of Technology letterhead, signed "R. P. Feynman" in a secretarial hand, with envelope. 1 sheet. Pasadena, CA, 12 February 1981. 270 x 218 mm. Light creasing, faint rust-mark from paperclip. Together 2 items. Very good. The rare offprint of Feyman's Nobel lecture presented by Feynman 15 years after he received the Nobel Prize. This is the first instance that we can recall in which an offprint by Feynman is accompanied by his original presentation letter. Also, we learn from this letter than Feynman used a secretary to send and sign letters like this which presumably he dictated. Another detail evident from this letter is that Feynman retained copies of this offprint as many as 15 years after it was published. His letter reads, "The enclosed reprint describes the development of my experiment. Sincerely, R. P. Feynman." Feynman enclosed a reprint of his entertaining Nobel lecture, which departed from usual practice in presenting an informal anecdotal account of his discovery, rather than a rigorously scientific presentation which he feared might bore his listeners.
