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.
You will notice a number of blanks in the Gibbons and
Michel numbers. Most of these are non-map stamps for which I do not
have the catalog numbers.
If you have a correction or addition to these numbers please let me
know. I will be happy to make additions and corrections.
