The document discusses different types of window displays used in retail stores: - Closed back windows have a glass front and solid back/sides allowing displays without interference from the store interior. - Corner windows face two perpendicular streets, maximizing visibility. - Open back windows have no back wall, so the store interior must be well-maintained. - Windowless displays rely solely on the interior to attract customers inside, common in malls. - Shadow boxes are small elevated displays for small items like jewelry. - Props support merchandise and themes while ensuring merchandise remains the focus. - Signage conveys information to assist customers' decision-making.
