The catalog lists each
stamp that appears in the various topical collections. Some of the
stamps appear in more than one place, and so will appear more than
once in the catalog. I have checked all the links for accuracy but if
you find errors, please let me know.
The Michel and Gibbons numbers for map stamps have been
added based on the Checklist of the CartoPhilatelist Society. The
Gibbons numbers end in 1993-94 because of the catalogs used. Michel
also ends about the same time. Those will be updated as they become
available to me.
If you have a correction or addition to these numbers please let me
know. I will be happy to make additions and corrections.
