This is a vintage postcard image of the Blue Grotto in Capri, Italy. The scene depicts the interior of a large sea cave. The cave's walls are dark and rugged on the left side, with a textured, rocky surface. The water within the cave is a striking, luminous blue, reflecting light and creating a surreal, ethereal glow. In the center of the image, a small wooden rowboat with two figures is visible. One figure is rowing, while the other is seated. The water's surface is relatively calm, with gentle ripples reflecting the light. The light source appears to be coming from the cave entrance, creating a bright, golden glow that illuminates the water and the boat. The overall effect is one of mystery, beauty, and tranquility. The postcard is labeled '1871 P.P. - Capri - La Grotta Azzurra' at the bottom.
