Paul Kos - Brieftauben (1987)

After a failed attempt to get the United States and U.S.S.R. to cast bells from the cruise missiles being removed from Europe and site them in the cities they were originally targeted for, 100 homing pigeons were used as a metaphor for striking missiles.

Each pigeon carried a bell and either a Soviet or U.S. flag in a small message capsule. From release points across Europe, they would accurately return to target.
