Mary's Delicious Cookies

Now, I am not sure who Mary is. It's just what the recipe card says.
I found this recipe when digging through my Grandma Pancake's recipes after she passed away. The neat thing is, the card says it's a recipe from my other Grandma, Grandma S. Oh, and yeah, it's handwritten by my mother. All the ladies in my life!
And now I am passing it onto my daughter. I love families.
