Vintage Children's Wallpaper

I am decorating our daughters' bedrooms (white, so no pictures included!) - and found a fantastic piece of vintage childrens' wallpaper on Ebay, which I will most likely frame.  I think the wallpaper is from the late 60's or early 70's.

I love the simplistic style and bright colours and my youngest daughter is mad about animals, so they should be a great addition to the family.
