The card is incorrectly addressed to “Union-City N.Y.” but was delivered to nearby Union City, New Jersey.
There is also a Union City, California, on the east side of San Francisco Bay. Might that have been why the card reached San Francisco, California on March 3rd? The postal clerks certainly haven’t given us any clues!
