We claim the ornamental design for a ventilation faceplate, as shown and described.
FIG. 1 is a front, left and top perspective view of a ventilation faceplate showing our new design;
FIG. 2 is an elevation view from the front showing the front side of our design for a ventilation faceplate, wherein, in such a preferred embodiment, an elevation view from the back is substantially a mirror image of FIG. 2; and,
FIG. 3 is an enlarged cross-sectional view taken along lines 3--3 in FIG. 2.
The broken line showing of environmental structure in FIGS. 1 and 2 is for illustrative purposes only and forms no part of the claimed design.
