1920s vintage picture book Daddy Domino art deco fantasy illustrations artist signed copy

1929 first printing Daddy Domino, by Mildred Plew Merryman, illustrations by Janet Laura Scott. This is a little worn and smudged, with old price in pencil on the title page as shown. Looks like this might be a artist signed copy? I have not been able to find a copy of an authenticated signature to confirm this.
