Mix thoroughly:
1 cup soft shortening (can substitute half or all with butter)
1½ cups sugar
2 eggs

Stir in:
2¾ cups flour
2 tsp. cream of tartar
1 tsp. soda
¼ tsp. salt

Roll into balls the size of walnuts.  Roll into mixture of 2 Tbsp. sugar and 2 tsp. cinnamon.  Place 2 inches apart on ungreased cookie sheet.  Bake at 400° for 8 to 10 minutes until lightly browned.  They will be slightly puffed up when taken out of oven, but will flatten out as cooling.
