This bookmark was made in the US for the Brooklyn, NY Tabernacle. This is a very RARE bookmark that was handed out by C. T. Russell at the 1913 Conventions of the International Bible Students. It is a religious celluloid bookmark with a picture of a man's head in an oval frame hanging from a grape vine. Underneath it says "Keep thy HEART with all dilligence for out of it are the issues of LIFE." This quote is from Proverbs 4:23. The back is a quote from I JNO 3:1 which says "Behold, what manner of love the Father hath bestowed on us that we should be called Sons of God." Also is says "When He shall appear we shall be like Him."
