Hi Everyone,
I sure hope I have started this thread in the correct category..
I have won a couple of duck stamps. I don't quite understand them though.
This one is a 1995 Oregon Upland Game Bird Stamp with an expiration date 6/30/96 with a license number (?) P037783.
Here are my questions...
Are these stamps part of "stamp collecting" because they are not like.. postage stamps right?
What does the purchaser do when they have one of these stamps? Do they use and stick them somewhere?
Is it for hunting birds only?
This "stamp" is inside its own notecard.
Here is the stamp. Thank you in advance to all who can answer and give any information / links to help me better understand these types of stamps:
