In a medium bowl, cream together shortening, eggs and 1 1/2 cups sugar. Sift together the flour, baking soda, cream of tartar, and salt into the creamed mixture (half at a time )... mix until well blended.
In a small bowl, stir together the 2 tablespoons of sugar, and the cinnamon. Roll dough in palm into near walnut sized balls, then roll the balls in the cinnamon-sugar mixture. Place them onto an unprepared cookie sheet, two inches apart.
Bake for 8 to 10 minutes in the preheated oven. Edges should be slightly brown. Remove from sheets to cool on wire racks.
2Makes approx 3 1/2 - 4 dozen depending on how large you roll them. I make them a little smaller than a walnut .. I usually get about 4 dozen.
Note: Check around 8 minutes into baking time, if bottom edges look a little brown, they are done. You don't want to over bake them.
