Used in Galaxy Science Fiction, which evidently contracted for artwork on a Work for hire basis (see, e.g., Vincent di Fate, Infinite Worlds [1997], p. 160), meaning the copyright resided with the publisher rather than the artist.
Works copyrighted before 1964 had to have the copyright renewed sometime in the 28th year. If the copyright was not renewed the work is in the public domain. These records are in the online catalog found here: http://www.copyright.gov/records .
