You want to capture that big moment and be able to keep it in your mind for a long time. You want to see it from far away and be able to read it, and have it grab you and bring you closer.
And you never want to get tired of it. It always looks fresh even when you don't.
Happy postcard making!
(Maybe I'll make a postcard of George Clooney. I wonder what he looked like as a little boy.)
