Curious Item of Sales Promotional Material

I just obtained a piece of Mark II literature that I had not seen in over 50 years of literature collecting.

It is a 4 page replica of the front, side and back that we've all seen. It is larger (11" x 14") and enclosed in an almost 'vellum' cover. I will add some pictures here curious if this is a previously known piece.Attachment 26708 Attachment 26707 Attachment 26710 Attachment 26711 Attachment 26709

Initially secured by three staples, they have released.

Is anybody familiar with this piece?

Happy 4th of JUly.
