This stained glass window depicting Jesus as the Good Shepherd was crafted in Germany in the late 1800's and displayed at an Expo in Toronto, Canada. It then made its way to a church in Brooklyn.
The window was moved from the Brooklyn church sometime around 1922 when that building was being demolished. Its new home was the Slovakian Evangelical Lutheran Church in Jersey City, NJ.
That church body disbanded around 1959. The window was purchased and then donated to Good Shepherd Lutheran Church, where it has hung ever since.

A plaque on the window states
In Memory of by Mary Stalter, Paul Balas |
