A label holder including a transparent cover member overlying a main body panel to form a label-receiving pocket connectable to a flat front face shelf without tape. The main body panel faces the front face of the shelf. The label holder includes an attachment structure for attaching the label holder to a horizontally oriented shelf lip by defining a U-shaped slot or gap. The attachment structure includes a concave portion, preferably U-shaped, that is elastically stretchable or deformable. This allows stretching of the attachment structure to accommodate different depths of the shelf lip.
