The ornamental design for a doll-shaped bookmark, as shown and described.
FIG. 1 is a perspective view of a doll-shaped bookmark, showing my new design;
FIG. 2 is a left side elevational view thereof, the side opposite being identical;
FIG. 3 is a front elevational view thereof; and,
FIG. 4 is a rear elevational view thereof.
The broken lines showing a face and earrings are for illustrative purposes only and form no part of the claimed design. The single detached portion of a braid in each drawing view represents the appearance at the bottom of each cut-off braid strand. No particular braid length is claimed, except for the single whole braid that goes through the clip in which the length shown is the length claimed. Furthermore the braids are in slightly alternate positions throughout the views.
