Although of some unknown vintage this baseball style hat with a medium length (6 stitch) brim is NOS ("New, Old Stock") from a militaria store closing. It isn't anything fancy and you could probably go to any mall and find a kiosk that would make one for you, but likely at greater cost. Looks to be made with iron-on letters. Snap style adjustable tab, mesh back for cool summer wear. Adult Large one-size-fits-all.
