Statue of Liberty was originally sculpted by Fredric August Bartholdi and copyright registration number 9939-G was issued to it in year 1876. Currently in US, the default term of copyright is life of the author plus 70 years while the sculptor died in year 1904, therefore, according to my understanding, the Statue of Liberty is in public domain and therefore, it is not a violation of copyright to sell photos of the Statue of Liberty. Besides, work published or registered before year 1923 is in public domain due to copyright expiration.
Note: In US, it\\\\'s a copyright infringement if someone engages in capturing photographs of copyrighted art work displayed in public places for commercial use without having express authorization from the author.
