Artwork on one of the Siekierkowski Bridge pylons on the western side of the city, located about 500 meters from the river.
Rurz is known from her usually pink cats, she is, one can say, social activist spreading positive and warm messages. You just cannot live in Warsaw and not know her cats.
And, yes, it's also a poke stop :D
