The LEARNING CENTER has information and articles mostly pertaining to the fundamentals of collecting of naval covers. First, we define what a naval cover is, and then what a postmark is. Next is a helpful section on what we call the “Locy System” for classifying naval postmarks–named for LCDR Francis Locy, who originated the system in the late 1920’s. For learning the basics, the article has great examples to actually see the differences.
Other sections in the Learning Center give background of collecting naval covers, and more specific areas of interest.
