I claim the ornamental design for a lighted rectangular frame for releasably supporting interchangeable signs, as shown and described.
FIG. 1 is a perspective view showing top, front and left side regions of my new design;
FIG. 2 is a left side elevational view thereof;
FIG. 3 is a right side elevational view thereof;
FIG. 4 is a front elevational view thereof;
FIG. 5 is a top plan view thereof, it being understood that a bottom view is a mirror image thereof;
FIG. 6 is a rear elevational view thereof;
FIG. 7 is a cross-sectional view as seen from a plane indicated by a line 7-7 in FIG. 1; and,
FIG. 8 is a cross-sectional view as seen from a plane indicated by a line 8-8 in FIG. 1.
The broken lines illustrate portions of the lighted rectangular frame for releasably supporting interchangeable signs that form no part of the claimed design.
