The Official Postcards Cancellations of the Zionist Congresses - An important catalog of the official Zionist Congress postcards that were published on the occasion of their existence - starting from the first Zionist Congress in 1898 until the Congress held in 1978, by Prof. H. RIEMER (from Switzerland). Published by The Society of Israel Philatrlists, Ohio 1980.
The catalog presents photographs of the official postcards issued in each Congress, starting with the first, and distinguishes between commemorative postcards and official postcards. Also, if there were congresses in which no official postcards were issued, they will not appear in the book (as the introduction specifies the difference between official postcards and souvenir postcards, as well as the congresses in which no official postcards appeared). The author even distinguishes between official postcards and ordinary postcards with special postmarks issued for the occasion of the Congress, and adds important details in this matter in the introduction.
