This work was published in the United States in 1962 with a copyright claim. Thus, its copyright was due to be renewed in c. 1990. I found no evidence of a renewal of copyright in this database, which lists all copyright renewal and registration records since 1978; thus, the image is in the public domain according to Commons:Licensing#United States.
This work is in the public domain because it was published in the United States between 1929 and 1963, and although there may or may not have been a copyright notice, the copyright was not renewed. For further explanation, see Commons:Hirtle chart and the copyright renewal logs.
