Feel free to ask questions too. I guarantee the authenticity of anything I sell, and will back it up with a return at any time policy if the authenticity is ever slightly questioned. I answer e-mail and return calls as soon as I am humanly able. All photos, autographed or not, are original, period NASA-issued photos unless specified. When I state it is a Kodak, that is not original NASA, but a high quality reproduction.
International shipping can be higher still, unfortunately.
More valuable items will be insured.
