Anti-bandit control

Anti-bandit controls (ABC) were overprints intended to prevent sale of stamps stolen in one locality from being sold in another.
 * The United States experimented with the Kansas-Nebraska overprints to this end beginning in 1929.
 * China handstamped town and city names as a control also, about the same time period.
