Permission: Delta Solar was put on display in 1977 without copyright notice. Prior to 1978, when the definition changed, sculptures that were permanently installed in a public place were considered to be published. As such, Delta Solar is in the public domain because it was published in the United States between 1923 and 1977, inclusive, without a copyright notice.
