I call upon all our citizens and all interested organizations to unite in appropriate observance of Pan American Day and Pan American Week
I do hereby proclaim Thursday, April 14, 1955, as Pan American Day, and the period from April 10 to April 16, 1955, as Pan American Week
Not by me.
I'm giving you my personal idea of how it could be done well.
