I claim the ornamental design for an trophy mount, substantially as shown and described.
FIG. 1 is a perspective view of a trophy mount showing my new design.
FIG. 2 is a right side elevation view of FIG. 1.
FIG. 3 is a front elevation view of FIG. 1.
FIG. 4 is a left side elevation view of FIG. 1.
FIG. 5 is a top plan view of FIG. 1.
FIG. 6 is a back elevation view of FIG. 1.
FIG. 7 is a bottom plan view of FIG. 1; and,
FIG. 8 is a perspective view of the trophy mount shown against a vertical mounting.
The broken lines in the figures are included to show portions of the trophy mount and articles in the environment that form no part of the claimed design.
