Dozen Tommy Armour "Small Size" Championship golf balls in four sleeves in the box. The small size references the fact that these balls were the small 1.62 inches in diameter "British" ball.  "Dyna90matic" is stamped on the side of each ball as the balls were made with the "new Dyna-Tension winding for extra power and uniform balance"  as advertised on the box.

Tommy Armour was once a giant in the game of golf.  He won the 1927 US Open, 1930 PGA, 1931 British Open, three Canadian Opens, the 1929 Western Open, and a total of 25 PGA Tour events.   "The Silver Scot," as he was eventually nicknamed, was endorsing clubs and balls for the Great Lake Golf Company by 1927 and continued to do so for a number of years before he was hired, by 1938, to design clubs for MacGregor.
