This panel from a golden age American comic book depicts a dramatic scene with two superheroes engaged in action. The foreground features a superhero in a dynamic pose, wearing a blue bodysuit with a yellow belt and yellow gloves. This character has black hair and is wearing a distinctive red cape with a yellow border. He's captured mid-motion, kicking a green barrel labeled "CEMENT" with his right foot.

Behind the kicking superhero, we see another character in a green robe with a blue cape. This second superhero appears to be in distress, holding onto the first superhero's cape. His expression suggests he's pleading, as evidenced by the text bubble above him that reads, "Mercy, mercy, Captain Marvel Jr.! Please don't throw me over!"

The background of the panel adds to the dramatic atmosphere. There's a yellowish-brown ground that the characters are standing on, with purple mountains visible in the distance. The sky is a light blue color, providing a stark contrast to the action in the foreground.

This panel effectively captures the excitement and drama typical of golden age comics, with its vibrant colors, dynamic poses, and the classic superhero conflict between Captain Marvel Jr. and another character.
