The image displays a group of four stylized, anthropomorphic bear-like characters rendered in black line art on a white background. Each character is upright and bipedal, featuring a simplistic body form that includes a prominent, elongated torso with minimally defined limbs. The figures possess distinct facial features and accessories1. The first character on the left is distinguished by an exaggerated headpiece resembling a baseball cap, placed backwards.

The legs are separated and slightly bent, giving an impression of casual posture.2. The second character, adjacent to the first, is adorned with a headpiece that might suggest a beanie or soft rounded cap with a decorative element like a leaf or twig on top. Features include large round eyes, a nose shaped like a heart, and a single line forming the mouth. The character extends its arms slightly outward as if in a welcoming gesture.3. The third character in the sequence sports a round hat similar to a bowler hat, perched atop two large, pronounced ears. The facial details include eyes that are larger and round, a heart-shaped nose, and a mouth consisting of a simple line.
