Whether you are a postal historian or a marcophilist, postal cancellations are central to the understanding of the postal artifacts that we collect. This course is designed to provide you with a very thorough background about cancellations. Collectors of every country and every specialization will want to attend this in-depth course.

The course is limited to ONLY 30 PARTICIPANTS so register now!

The course will include three major topics:

• • Classification & Categorization Systems
  • Types of devices
  • Uses

The presentation materials will be profusely illustrated with cover examples of each topic.
