I believe the correct answer is relief.

Unlike freestanding sculpture, relief is the type of sculpture which is created to be viewed from one side only. It is a sculptural technique where the sculpted elements remain attached to a solid background of the same material, whit difference in their attachment to the background material. Types of reliefs are: high relief (more than 50% of the depth is shown), mid-relief, low-relief, shallow-relief and sunk relief.
