T-Shirt Tシャツ

This design features a charming cartoon penguin dressed in a professional uniform. The cute bird is wearing a dark blue peaked cap with a circular yellow emblem and a smart blue and yellow striped necktie. It is standing upright and holding a brown leather briefcase in its wing, looking ready for work. The character has a round, chubby body with large black eyes and a small orange beak, portrayed in a clean style against a plain light gray background.
