The image shows a wall-mounted display of yellow level meters, which are used for measuring horizontal and vertical angles in construction and engineering. The display is organized in rows and columns, with each level meter placed on a separate peg. The yellow color of the meters is prominent against the white background of the wall, making them easily visible and distinguishable from other items. The display appears to be part of a store or warehouse, as indicated by the presence of similar items in the background.
