White border; real photo postcard; no publisher printed.
No postmark and no stamp present. Divided-back 'POST CARD' (MESSAGE / ADDRESS) with a vertical divider; unused. A small pencil notation is written sideways in the lower-right (address) corner, apparently initials plus a number (looks like 'RMLD' over '400'), likely a dealer/collector mark rather than correspondence. Front is a white-bordered black-and-white real-photo view of a waterfall.
