PATENT OFFICE 32ND AND ROANOKE ROAD TEL. VALENTINE 6969 KANSAS CITY, MISSOURI February 19, 1938, Dr. Forrest C. Allen, Athletic Department, University of Kansas, Lawrence, Kansas. Dear Phog: Once again you have proven yourself the old master in the game you love so well. I am pretty darn busy this morning getting details cleaned up so that Mrs, Servey and myself can get away to Mexico City. I just can't leave, however, without sending you these few words of congratulation. We heard part of the game when we were driving down to the Philharmonic Concert last night. Then I got off into sanebody's concert in C minor and got lost. Then I went to the telephone later and called the Star for the final results and what a thrill. Again with my heartiest congratulations, I am Cordially yours, DFS :W Den F. Servey
