In 1928, Hampton moved to Washington, D.C. and shared an apartment with his older brother Lee. Hampton worked as a short-order cook until 1943 when he was drafted into the United States Army Air Forces. He served with the 385th Aviation Squadron in Texas, Hawaii, and in the jungles of Saipan and Guam. The segregated unit was noncombatant and duties included carpentry and maintenance of airstrips. Hampton built a small shrine-like object during his time in Guam which he incorporated into his larger artwork later.
