Here's one from the _Woman Who Toils: Being the Experiences of
Two Gentlewomen as Factory Girls_, by Mrs. John Van Vorst and
Marie Van Vorst (New York: Doubleday, Page & Company, 1903):

DEDICATION

            To Mark Twain
In loving tribute to his genius, and
to his human sympathy, which in
Pathos and Seriousness, as well as
in Mirth and Humour, have made
him kin with the whole world:--
               This book is inscribed by
          Bessie and Marie Van Vorst.
