I would suggest taking a photo under different lighting conditions, uv is a thought but being graphite based, IR would seem best to highlight the writing, but I could not say which would be better, same angle from beside the camera or from the side slightly above the plane of the bespoke postcard. Oh if I'm not mistaken, postage date suggests 111 years old. Edit about 30 min later. A thought, might be (iron gall) ink and not pencil. UV might be useful.
