I just came across an intriguing stamp in an old book of Psalms that I purchased from Rabbi Shlomo Poupko's library. Below are photos, here is the full text of the stamp: "Shomrei Sabbath Colonie, Greater Boston; a traveling home, a camp for children and convalescent . Home in honor of our beloved President Franklin D. Roosevelt. ELECTION DAY===11-5-40"
FDR was indeed re-elected as President on Nov 5th, 1940
The Organization apparently stamped their books as a bit of election day advertisement for FDR. I was not able to locate any information as to this organization or what became of it.
