I recently found a postcard franked with a 1-cent Franklin stamp on eBay with a Tau, Samoa Doane cancel. This postcard is the 9th Tau Doane postmarked item in my census and is labeled accordingly. This card is similar to most of the Tau Doane items in the census; it is addressed to Rock Falls, Illinois, and was postmarked on June 23, 1909. The stamp appears to be from the bottom of a sheet of Franklin stamps.
The updated census is below.
