Cute & bookish decorating idea

For booklovers who like to paint/decorate: I just saw this photo on Facebook (posted by Lori McHale, executive director of the nonprofit Designing 4 Hope in Limerick, which makes over the bedrooms of very sick children. It's a repost of a photo by The Cottage House in Minneapolis.)

I can see it on stairs to a child's room or cozy attic. Or in a library. Adorable.
