The Dutch were the first Europeans to settle in the Hudson River Valley, and the town of Kingston was one of the earliest towns.

Located north of the city of Poughkeepsie, and south of what is now the city of Albany, Kingston was the first capital of the State of New York from 1777-1797.

Dutch influence can still be found today in many of the old towns and cities of the Hudson Valley, and the State of New York maintains several museums and historic sites related to Dutch inheritance.

In Kingston, the Dutch Reformed Church was first organized in 1659.
This building was erected in 1859, the fifth church on the site.
The church, a National Historic Landmark, is considered the “perfect example” of a Renaissance Revival church.
Examples of the best 19th century artisans and craftsmen (Tiffany windows, a Moller organ, e.g.) still adorn the structure.

The postcard photograph was published by the Kingston Souvenir Company about 1920.
The company logo featured a swastika design that is jarring to contemporaries.
We have seen in other postcard stories that, until it was appropriated by the Nazis, the swastika was often applied as a good-luck symbol to postcards.

This postcard was not mailed.
Because of its excellent condition, I suspect that it was saved in a collection of souvenirs.
Many postcard collectors of the first half of the 20th century collected specific categories of cards – and this one could have been saved with “Churches”, “History”, “New York” – or under some other designation.
