The Judaica Thematic Society was formed in 2005. Originally it was formed for collectors of the theme of "Judaica On Stamps".
The society tries to specialise in "Judaica" that appears on stamps from all over the world.
"Judaica" can appear in all forms on these stamps, such as Synagogues, Hebrew Wording, Star Of David, Jewish Festivals, and Jewish Personalities. This list can be endless with many, many other themes within "Judaica" Amongst the collectors within the society, there are some collectors of Postcards depicting Judaica, such as Synagogues, and Anti-Semitism for example.
There are certainly no rules in collecting - and that is what makes collecting "Judaica", and this society so interesting.
The Judaica Thematic Society publish a monthly newsletter.
