The O. E. Rolvaag Letters date from 1927 to 1928 and include two letters written to critic Harry Hansen of the New York World. In the first letter, written on St. Olaf College letterhead and dated June 4, 1927, Rolvaag remarks, "I've been waiting for your review of Giants in the Earth with a good deal of anxiety. Now I hasten to thank you sincerely for your kind, sympathetic review of the book!" The second letter, dated Sept. 17, 1928 and written on the letterhead of the Norwegian American Historical Association (of which Rolvaag was Secretary), is written in response to a political question posed by Hansen. Also present is the corrected typescript which Rolvaag enclosed for possible publication, in which he writes "Not yet have I been able to make up my mind for whom to vote. I am, by nature I think, a republican. Hence, I should vote for Hoover. But I am so thoroughly disgusted because the religious issue has been injected into the campaign that I may actually be goaded into voting for Al Smith although I am a Lutheran."
