TLS signed “T. Roosevelt,” one page, 6.5 x 7.75, The Outlook letterhead, September 5, 1911. Letter to Marie F. Ryerson, in full: "I wish I could accept but it is a simple impossibility. I have received literally thousands of similar requests and with the best wishes in the world it has proved impossible for me to accept one in a hundred of these invitations. I deeply appreciate the courtesy and kindness of those who ask me to speak but you have no conception of the drain it is upon me even to accept the very limited proportion that I am physically able to accept, and I could not greatly increase this proportion or accept more of the invitations that come to me without absolutely abandoning all thought of any other work." In fine condition, with toning from prior display. Encapsulated in a PSA/DNA authentication holder.
