Peckerwood Midwest is a white supremacist gang based primarily in Missouri, active both in prisons and on the streets. The gang's "patch" tattoo consists of a diamond-shaped swastika inside a larger Iron Cross. Inside the swastika are SS bolts; outside the Iron Cross are the numbers 23/16 (which stand for "White Power"). The Iron Cross will often contain a wood grain, meant to symbolize "peckerwood" (often shortened to "wood").
Members sometimes use a two-handed handsign in which both hands form "pistol" shapes angled upwards so that the index fingers touch.
