Hi, one foreign collector asked question about the Feather seal on the Hawaii cover. I am not familiar with it, does anyone know if it has any special meaning related with the mail? Is it personal seal?
Here is the English translation of the answer: "The feather seal is personal seal put on the cover (especially on the address characters) so that nobody would be able to modify these characters."
Hope it would give some help to the foreign collectors.
