Portrait holders, also known as frames, are a common way to display artwork or photographs. They come in a variety of shapes and sizes and can be made from a variety of materials such as wood, metal, plastic, or glass. Frames are used to protect the artwork or photograph from damage and to enhance its appearance. Frames can also be used to add a decorative touch to a room or to create a focal point in a space. Frames can be hung on walls or placed on shelves or tables.
