Charles A. Lindbergh Letter Forwarding Aircraft Proposal to Harry Knight (1934)

An autograph letter written by Charles A. Lindbergh on his 39 Broadway executive stationery, dated June 13, 1934, addressed to Donald A. Hall Sr. in San Diego. Lindbergh acknowledges receipt of Hall's correspondence and confirms that he has forwarded Hall's technical proposals to Harry Knight in St. Louis, one of Lindbergh's original 1927 financial backers. Lindbergh notes that Knight is among the group actively interested in backing the manufacture of Hall's proposed low-wing monoplane design and promises to inform Hall as soon as an organizational response is received.
