pop-up card, four ewes.

This is drawn in pencil and appears to have been done by a child. It was an attempt to get the sheep off the center. It was never mailed.

Two straps with a mountain creases fold into a collapsed W shape with the ends glued to the background thus creating two new short spine creases on either side of the original central fold.

It's a different take on the pun "Happy birthday two ewes," here "Kaaaad (card) four ewes." Frankly, it's not that funny.
