ALT A sepia-toned, cartoon-style illustration of a laboratory table. In the foreground, a single, illuminated Petri dish sits on the right, showing a bright, light-green mold (representing Penicillium mold) growing on a dark medium. To the left are a rack of four test tubes and the base of a vintage microscope. The background shows the shadowy outlines of a messy lab bench with various glassware and bottles. The scene evokes the accidental discovery of penicillin by Alexander Fleming.

ALT A color illustration shows four people leaning over a table to look at a glowing golden pocket watch. A man in a suit in the center holds the watch, which emits a bright yellow light. To his left, another man in a suit looks on with a hand to his chin. To the right of the central figure, a woman with red hair and a man with gray hair and glasses peer at the watch. A large, dark blue logo with a yellow sunburst is visible on the wall behind them.

ALT A digital illustration depicts a muscular man performing a dynamic martial arts kick against a bright, gradient-colored sky. He is captured mid-air, leaping with his right leg extended forward in a powerful kick, while his arms are bent at the elbows, fists clenched, as if executing a strike or block. The man's torso is bare, revealing his well-defined physique, and he wears dark, loose-fitting pants that appear torn at the knee. Behind him, silhouetted against the vibrant sky, is the United States Capitol Building in Washington D.C., rendered in a stylized, simplified manner. The sky transitions from a deep blue at the bottom to a lighter, almost white shade at the top, with a bright, sun-like burst of light emanating from behind the man, creating a halo effect around his form. The overall style of the image is illustrative and painterly, with smooth gradients and soft edges, giving it a dreamlike or heroic quality.

ALT A digital illustration depicts a woman in a red outfit hugging a person with curly black hair. She wears a red hat adorned with pink roses and has a sly smile on her face. Her eyes are focused beyond the person she is embracing. In her hand, hidden from the person she is hugging, she holds a small glass bottle with a skull and crossbones symbol, suggesting poison. The background has a dark, swirling teal hue, adding to the ominous and suspenseful mood of the image.

ALT In the foreground, a woman in a spacesuit stares at the moon. In the background is NASA’s Mercury capsule, faded NASA blueprints, and a tilt table with a scientist recording test results.

The background is dark with a spotlight shining on the snowman.

ALT A large crowd of Wide Awakes, a Republican youth movement during the 1860 presidential election, marched wearing capes and with lanterns and torches on a dark, foggy night in support of Abraham Lincoln. The lanterns cast a warm glow, illuminating the marchers' faces. In the center of the crowd, a banner reads "LINCOLN," and another banner reads "WIDE AWAKE." The American flag is visible in the background.
