Dear Colonel Lindbergh:

For the exhibition of the Lindbergh apparatus
at the New York World's Fair, which you authorized me
to permit, we are now asked for permission to reproduce
in greatly enlarged form the following plates from "The
Culture of Organs":

Plate I, page 18.

Plate II, page 35.

Plate IV, page 39.

These are to be used as placards to be displayed
with the apparatus. John believes they will help the
public to understand the pump better. If you have no
objections, we will ask Mr. Hoeber for permission to
reproduce these plates.

With best regards, believe me

Colonel Charles A. Lindbergh,

Illiec,
