The three Oakland cards on this page were mailed from Oakland on 12/29/1906 to Mrs. M. Bendon in Boston. The post office struck out "Highlands" in the address and rubber-stamped "Have your Mail Addressed where you wish it delivered." on each. Weidner 170 is unsigned, Weidner 171 is signed "From May And John", and Weidner 174 is signed "Mary S." (not "May S.").
Weidner 170. Weidner 171. Weidner 174.
