[Illustration: THE WHITE HOUSE WASHINGTON December 5, 1922. Dear Mr.

Jenkins: Please accept my thanks for the radio photograph which you were

good enough to send to me. The production of a picture in this fashion

is certainly one of the marvels of our time and I am under obligation to

you for sending me this handsomely mounted copy which will be preserved

as a very much prized souvenir. Gratefully yours, Warren G Harding Mr.

C. Francis Jenkins 1519 Connecticut Avenue, Washington, D.C.]
