Mr. and Mrs. Bainbridge lived in Lacona, a village of Oswego County in west-central New York.
The village is close to the mouth of the Oswego River on Lake Ontario.

In December of 1919, the Bainbridge family received a Christmas postcard from Aunt Alice and Belle.
It is not possible for us to know if Belle was a daughter of Aunt Alice -which would make her a cousin of Mr. or Mrs. Bainbridge.
Aunt Alice mailed the postcard from Syracuse, the economic hub of the central New York region.
Syracuse began as a salt-mining camp in early Colonial times, but became a commercial and transportation center with the coming of the Erie Canal and then the railroads.

The face of the postcard is a small drawing of a rural home in wintertime.
The scene is adorned with large poinsettias.
On the right side of the face, a Christmas verse is printed:
“O let us make Christmas a time of light,
With puddings ablaze and candles aglow!
And let us make Christmas a time of right,
When love and goodwill to all we show!”
On the reverse, Aunt Alice has inscribed, “May you all have a Merry Christmas is our best wish”.
In addition to the one-cent stamp, a Red Cross stamp for 1919 is affixed to the reverse.
One hopes that Mr. and Mrs. Bainbridge were delighted by the Christmas postcard from Aunt Alice and Belle, and that each of them enjoyed a blessed Christmas.
