The name of the speaker is Ioannis Derziotis, the lecture is "The Desirable Government." In the lower part of the bill we have day and month, Sunday October 19, but no year. "A Desirable Government" was a booklet written by Rutherford in 1924 and translated in several languages. (I have a copy in Italian language dated 1924.) So the day must be Sunday, October 19, 1924. The other possible date is far-off, Sunday October 19 1930.
So the only correct date of the bill can be Sunday, October 19, 1924.
The name of the speaker is Nick Konstantopoulos, the lecture is “Organization of Satan’s Empire.” In the lower part of the handbill we have day and month, Sunday 25 January, but no date. In the years 1922-1925 there were a series of resolutions at the Bible Students Conventions against Satan and his Empire (See W56 8/1 pp. 467-74). The handbill can be related to a doctrinal change in progress about Armageddon. In the Watch Tower of July 15, 1925, the leading article entitled “The Remnant” set forth for the first time that Armageddon is not a disorganized “time of trouble, such as never was since there was a nation,” or a violent, anarchistic battle between capital and organized labor, but is a universal fight between Jehovah God and the entire organization of Satan the Devil in heaven and on earth. Note that in those years the “System of things” was called “Empire of Satan”.
Well, the only possible date for this bill is: Sunday, 25 January, 1925
