These publications illustrate more artworks that are now in the public domain in the United States because the artists did not file copyright renewal applications within the one-year renewal window at the end of the 28 years following the first publication. All of these artists died fewer than 70 years ago, so these artworks are potentially protected by copyright in countries that calculate copyright protection based on the life of the artist.
