Ex. meeting at Stern's
Rodney St. home
As we now know quite well, Papa was a member of B'nai Zion (a.k.a. Order Sons of Zion) a Zionist fraternal organization and mutual support society closely affiliated with the Zionist Organization of America. Papa's chapter formed earlier in the year and Papa (who like many Zionists of his day believed that Jews should trade their downtrodden image for the image of strong, competent "muscle Jews") successfully lobbied to nickname it "The Maccabean" after the Jewish warrior heroes of old.
The "Ex. meeting" mentioned in this entry is most likely an executive meeting of The Maccabean, which Papa would have attended in his capacity as Master of Ceremonies. It looks like the meeting took place at "Stern's Rodney St. home" in Brooklyn's Williamsburg neighborhood, though I'm not quite sure if I'm reading the name "Stern" correctly. Let's take a closer look:
