I claim the ornamental design for a sports themed picture frame, as shown and described.
FIG. 1 is a perspective view of a sports themed picture frame, in particular a football themed picture frame, where the sports themed picture frame includes (1) a support for a picture, and (2) a display base.
FIG. 2 is a perspective view of the sports themed picture frame of FIG. 1, without the picture.
FIG. 3 is a front view of the sports themed picture frame of FIG. 1, without the picture.
FIG. 4 is a right side view of the sports themed picture frame of FIG. 1, without the picture; and,
FIG. 5 is a rear view of the sports themed picture frame of FIG. 1, without the picture.
The broken lines shown are included for the purpose of illustrating portions of the picture frame that form no part of the claimed design.
