I just obtained these Post Cards. These post card were mailed from the Groveville and Yardville Post Office's on the last day they were independent Post Offices, after this date they were Trenton Branch Post Offices. .
There is no writing or message on the reverse of these Post Cards, they were mailed only to obtain an official Groveville or Yardville post mark on this historic date.
.
As we can see Pete Larkin was the Yardville Postmaster at the time, I can only guess that Groveville's Postmaster was Betty Stackhouse, at he time.
