This design features a black and white illustration of a cute, cartoon-style koala. The koala is holding a sign that reads "BABY ON BOARD". The sign has a simple, rectangular shape with a dashed border, and it's held up by the koala's paws. The koala itself has a friendly expression, with big, round eyes and a small smile. The overall image has a playful and endearing quality, likely intended to evoke a sense of joy and anticipation for a new baby.
