This panel is a vibrant example of a golden age American comic book scene. The focal point is a woman with long brown hair, styled in a typical 1940s fashion. She's wearing a yellow hat and a matching yellow shirt, which creates a striking contrast against the pink background.

The woman is positioned on the right side of the panel, her body turned slightly towards the viewer. Her right hand is raised, as if she's waving goodbye or bidding farewell to someone. This gesture adds a sense of movement and emotion to the scene.

To the left of the woman, there's a blue door. This door likely represents an entrance or exit point in the story, possibly symbolizing a transition or change in the narrative.

The background is predominantly pink, which was a popular color choice in comics of this era. It helps to create a warm, intimate atmosphere and draws attention to the characters in the foreground.

At the top of the panel, there's a yellow banner with black text that reads, "A moment later, the train pulls out." This text provides context for the scene, suggesting that the woman has just waved goodbye to someone who has boarded a train that's about to depart.

There's also a speech bubble coming from the woman that says, "So long, Larry." This dialogue confirms that she's waving goodbye to a specific person named Larry, adding a personal touch to the scene and hinting at a relationship between the woman and Larry.

The overall composition and style of the panel are quintessential of golden age comics, with bold colors, clear lines, and dramatic poses that were designed to capture the reader's attention and convey the story efficiently.
