These images are also in the public domain in countries that figure copyright from the date of death of the artist (post mortem auctoris), in this case William Wallace Denslow died March 29, 1915, and that most commonly runs for a period of 50 to 70 years from the last day of that year.
The people greeted Dorothy kindly, and invited her to supper and to pass the night with them; for this was the home of one of the richest Munchkins in the land, and his friends were gathered with him to celebrate their freedom from the bondage of the wicked witch.
Dorothy ate a hearty supper and was waited upon by the rich Munchkin himself, whose name was Boq. Then she sat down upon a settee and watched the people dance.
When Boq saw her silver shoes he said,
"You must be a great sorceress."
"Why?" asked the girl.
"Because you wear silver shoes and have killed the wicked witch. Besides, you have white in your frock, and only witches and sorceresses wear white."
