Pre-War baseball cap

A red baseball cap. The kind you would wear on those hot summer days before the Great War. Pre-war baseball caps can be found in various places/shops in the Wasteland. One of these is given to the player during the "Enjoy your party" section of the Growing Up Fast quest during their 10th birthday party. Talking with Stanley, one of your father's friends, and asking if he has anymore gifts will result in the free cap, other options may not result in receiving the cap.

There is a unique variant of the baseball cap, the Takoma Park Little Leaguer Cap.

This headwear can also be looted off of Overseer Mack's body if you killed him in Trouble on the Homefront.

One hat can be found at the Flash Memorial Baseball field by Arefu.

At the star of Escape! if you search the dresser in you room there is a bunch of vault suits and a Pre-War Baseball cap (sometimes is replaces with Pre-War Hat (Presumably if you don't get the Baseball Cap of Stanley Armstrong.)
