Who was Mr. Garrison, and why did Whitney feel the need to maintain this correspondence with a maybe printer, maybe lawyer, who had lost all his money?
These papers likely came to La Guardia through a subpoena of Whitney's papers, as the NYSE was under intense scrutiny from the gov't in the wake of the 1929 crash. Whitney was frequently called to D.C. to testify, and (judging from the amount of mail La Guardia had in his files) likely getting dozens of letters a day from lunatics nation-wide. 6/
