This panel is from a classic golden age American comic book, likely dating back to the 1940s or 1950s. The scene depicts a dramatic moment of action and discovery.

In the foreground, we see a woman in a green swimsuit with red hair. She's positioned in a defensive stance, crouched down with her arms outstretched, as if preparing to brace for impact or to catch something. Her posture suggests a mix of anticipation and concern.

The woman is standing on what appears to be a rocky or sandy surface, possibly a beach or cliff edge. The background is dominated by a large, dark cloud or plume, which adds to the sense of danger or mystery in the scene.

The focal point of the panel is a rock that the woman seems to have just thrown or is about to throw. This action is emphasized by the text "BUT AS NYOKA TOSSES THE ROCK IN..." at the top of the panel, indicating that this is a crucial moment in the story.

The rock itself is the source of the woman's concern, as evidenced by her speech bubble which reads, "WOW! THERE MUST BE SOME STRONG CHEMICAL IN THAT WATER THAT SOLVED THE ROCK." This suggests that the rock has been altered by some mysterious substance, possibly causing it to react or change in unexpected ways.

The panel is drawn in a typical comic book style of the era, with bold lines and exaggerated expressions. The color palette, while limited, is vibrant, with the green of the woman's swimsuit standing out against the darker tones of the background and the red of her hair.

Overall, this panel captures a moment of suspense and discovery, leaving the reader curious about what will happen next and what secrets the mysterious rock might hold.
