The image shows a display case filled with various types of tubas. The tubas are arranged in rows and columns, with the largest tuba at the bottom and the smallest at the top. There are six tubas in total, each with a unique design and color. The instruments appear to be made of brass and have a shiny, polished finish. The case is made of glass, allowing the instruments to be seen from all angles. On the right side of the case, there is a blue plaque with information about the instruments. The background of the image is a white wall with a wooden floor.
