FIG. 1 is a perspective view taken from the top, front and right side of an
entry for a bathing tub showing my new design;
FIG. 2 is a top plan view thereof;
FIG. 3 is a front elevational view thereof; and,
FIG. 4 is a right side elevational view thereof, the left side being the
mirror image of the right side.
The fragmentary broken line representation of a bathing tub with which the
claimed design may be associated is for the purpose of illustration only,
and forms no part of the claimed design.
