A story about the most famous nanny in the world and the children from Czereśniowa 17 - in a new translation by Marcin Mortka and with original illustrations by Mary Shepard.

When Mary Poppins answers a newspaper advertisement and shows up at the Banks' house, the four children quickly discover that she is a nanny unlike any other. Who is this strange person in a blue coat and a parrot-headed umbrella? Mary rides up the railing to the second floor, has an unusual uncle floating from the ceiling, understands the language of dogs and sticks the stars to the night sky ... She promises little Banks that she will stay with them until the wind changes, and one day she actually leaves (actually flies away) - but don't worry, not forever!
