The name of the town is Żarki. In the Polish language, a noun is declined in the sixth (the locative) case when the preposition "in" ("w" in Polish) is used. Since it is a plural noun, "in Żarki" is declined as "w Żarkach".
Forgeries of Żarki stamps are plentiful!
In the genuine stamps, the first person in the group of three is in standing position, while in forgeries this person looks more like he's kneeling. Besides, the paper in the genuine stamps is white under ultraviolet light.
