The Invitation is intended as a special commemorative document. The PIC sent out one million invites to early supporters of Barack Obama. Unfortunately, it is not a ticket, nor does it entitle you to receive one. But it is a unique keepsake for your family. The Invitation was printed from a hand engraved plate for a limited edition. Here is an article from the New York Times regarding the printing. http://www.nytimes.com/2008/12/21/nyregion/thecity/21prin.html?hp
My daughter was excited about the Inaugural Invitation. I didn't see where it was a ticket to anything. So, we assumed it to be a nice commemorative item for Obama's Inauguration. It will look lovely in a picture frame. I'm glad I received the Invitation.
We received our invitation to the Douglas wedding.
If you received an invitation to the wedding then you do not need to bring the invitation to prove you were invited. If you never received an invitation to the wedding then it is not etiquette to attend the wedding and you would be considered crashing the wedding.
