In 1967, three years after Bok's death, Petaja founded the Bokanalia Memorial Foundation. The foundation was set up "with the help and encouragement of Harold Taves of Seattle and Ray Bradbury of Los Angeles and the Golden Gate Futurians of San Francisco . . . . The avowed intention of Bokanalia is simply to keep the great imaginative art of Hannes Bok from slipping into oblivion, and to make new (better than pulp) prints available to his many admirers all over the world".
