A delightful retro illustration of a brown bear in a humorous situation. The bear is taking a bath in a bathtub that resembles a car with four wheels underneath. The bathtub is filled with thick, frothy soap foam. The bear sits on a rustic wooden stool, sporting a playful yet slightly annoyed expression. Its eyes convey irony and boredom. The overall design is whimsical, with a touch of vintage charm, making it perfect for a black t-shirt.
