Collection of five ALSs, each signed in full, dated between 1920 and 1938, including one as first lady on White House letterhead. The ALS as first lady reads, in part: “I am sincerely thinking of adding a chapter…taking as my subject ‘As a White Court Guest.’ I should make a good story of it which would not be better than you deserve—it couldn’t be.” Another, on both sides of a black-bordered mourning card dated shortly after Calvin Coolidge’s death, in part: “This is a short note because I have so many to write…I do want you to know how much I appreciate your thought and your love.” Two letters are accompanied by their original mailing envelopes filled out in Coolidge’s hand, one including a franking signature in the upper right. Also includes an unrelated mailing envelope bearing her franking signature. In overall fine condition. RR Auction COA.
