This Charity's first stamp like label was released in 1902, and they have issued thousands of different fundraising seals. They are attractive, and historic. Interesting "Related Material" abounds, such as tags, proofs, essays, membership certificates and even tin litho donation banks. Illustrated here are what had been 25 cent examples. Cinderella collector and expert, Michael Hide says, "... JNF material has risen sharply over the last 10 years or so. One can still find deals but they are few and far between. Also, many JNF items were actually issued out of their New York office."
Not to be confused with the Jewish seals listed in Mosbaugh's US All Fund Catalog, JNF seals were sold in many countries. After the British abandoned the Post Offices in 1948 they were used in Israel as postage stamps with various hand stamped overprints. The 2009 Catalog of Jewish National Fund, by Ralph Phillips and Izhak Wayman, lists 4200 different thru 2004. Another great JNF catalog is Rochlin's Handbook of the Issues of The Jewish National Fund.
