This is a cute little individual set of salt and pepper shakers that were used in 1950's on American Airlines flights. They are cube shaped and measure 2 1/2 inches tall and 1 inch in width and depth with silver colored tops. They are both marked USA on the bottom and 1 has the number 23 and the other has the number 3. They are in excellent condition with no chips or cracks.
