1950's Christmas window decorations

I remember this, it was cute and easy to apply, as I recall you also needed to buy a package of thin cardboard stencils. My family used this in the 1970's and by then it was available in an spray can so it was easier to put on. It did smell a little when you put it on, but the big problem was that you had to scrape the window to get the stuff off, it dried really hard.
