This book is a classic from childhood. There are few children (or adults!) who I think could not quickly offer up a quip (or a song) from Mary Poppins. We don't mind her strictness or her primness because know, deep down deep, she's full of the fun we're looking for in life.
This bookmark features my own watercolor illustration of Mary Poppins and the London skyline on one side and vegan leather on the other (dyed a rich black tone), stitched together to create a durable, 4mm-thick rigid bookmark.
