A series of numbered garage doors set against a backdrop of residential buildings and a clear blue sky. The garages have a concrete appearance with white doors, and some greenery is visible around them. In the background, there are two buildings: a mid-rise apartment complex with balconies and a cream-colored building with a red tile roof.
