Mix together thoroughly the shortening, sugar and eggs.

Sift together and stir in flour, cream of tartar, soda and salt. Roll into balls the size of small walnuts.

Roll in mixture of 2 tablespoons sugar and 2 teaspoons cinnamon.

Place 2 inches apart on ungreased cookie sheet. Bake 8 to 10 minutes in medium to hot (400 degrees) oven until lightly brown but still soft. These cookies puff up at first, then flatten out with crinkled tops.
