I was hoping that Ohio and Oregon would appear today although I could not find them in the series on State flags.
I have sent those stamps in the past, but didn't think of them for today.
postcards of these stamps would also be a great idea.
Love those postcards. I'm not sure that I have received any of them, but I see them often on the Internet. I hadn't noticed they exist also as stamps.
I am not sure I've ever seen one in real life.
