Japanese student Masujiro Kiru found this photo in a scrapbook left by his father. Apparently the scene is Tsientsien Street in Hopeh, China, around 1942. UFO enthusiasts note that two people appear to be pointing to an object in the sky. It could be a bird, it could be a hat, it could be man-lizards from Aldebaran. You decide.
