Catalogues for chess cancels are few and far between. In fact, the collector must either search on diverse private internet sites or trawl through relevant auction platforms. However, this does not give an overview.
It is generally accepted that the interest of collectors decreases when they do not have a source to inform themselves about their field of interest. This interest needs to be sustained.
It is the target of this catalogue to fill a gap that occurred with the demise of the Checkmate catalogue in August 1988. Now, (almost) all issued cancels will be illustrated in detail in one work.
During the project, we were able to fill many gaps. At the same time, however, we have to admit that, despite every effort, this new catalogue also is not be complete.
It took a vast quantity of time to record all cancels and appropriate images in a database. This is impossible to be done by each collector himself. But we have carried out this task and make it available for all collectors.
The new edition heralds a new era. The catalogue has not only exceeded the number of 5.000 postmarks, but also offers two epochal innovations compared to previous editions.
a. For each postmark, documents (covers) are shown that were issued on the occasion of the postmark. If possible, these should only be official covers, but in all cases this could not be determined properly.
b. Comparative prices were determined for all special postmarks (except private postmarks). This is completely new and the price evaluation methodology is disclosed transparently.
