This is a very interesting postcard to me. It has perforations around 3 edges, and apparently folds open - so the writer can have an entire sheet for correspondence. If you click on the photos to enlarge, you will see the perforation holes.
I don't remember how these came to be in my collection, but I have a total of 3 - all from Canada.
