The ornamental design for an elevatorwallsurface having decorative mirror, as shown and described.
The FIGURE is an orthographic view of an elevator wall surface having decorative mirror.
The broken-lines illustrate environmental structure and form no part of the claimed design. In particular, the broken lines showing the side, top and bottom walls of the elevator cab are flat and unornamented.
The claimed design in the FIGURE concerns a rear wall divided into three panels; the wall is divided into a center mirrored panel and two glass panels flanking either side of the center mirrored panel. The rear wall includes vertical seams dividing the panel; the seams are visible in the front view but are in the same plane as the illustrated panels, with no depth.
