Sokolow tombstone

Any chance any of you know where this tombstone is? What city, what place?

It's a picture from the Yizkor Book, but there's no caption.

Jewish tombstones

Fragments from dozens of Jewish tombstones were discovered during renovations in a Polish town near the former Nazi death camp Treblinka.
The fragments were found last week in the eastern town of Sokolow Podlaski as work began on a terrace leading to the shops located at a marketplace there.
