United States territorial acquisitions
The Panama Canal Zone was an unorganized US territory located within the Republic of Panama. It was established under the Hay–Bunau-Varilla Treaty in 1903 and disestablished in 1979 under the Torrijos–Carter Treaties. Panama gained full control over the Panama Canal in 1999.
William B. Van Ingen
The Panama Canal murals were executed on nearly of canvas and depict the excavation of the canal. They are mounted in the Panama Canal Administration Building in Balboa, Panama. Van Ingen agreed to produce the murals at $25 per square foot. The paintings are apparently the largest group of murals by an American artist on display outside the United States .
