Dear Max,

Thank you for your information, it is very helpful for me.

Another question:
You said the local rate between 1900-1902 is 2 pf for a postcard, but attached is from a page of Michel Germany postage rates book, it shows that the 2 pf for the local rate for a postcard is from 04/01/1900 to 06/30/1906, it is different with yours.
