Rudolph de Harak designed over 50 record covers for Westminster Records as well as designing covers for Columbia, Oxford and Circle record labels. His bright, geometric graphics can easily be distinguished and recognised.
Katayama worked in several art and design disciplines from graphic design and sculpture to environmental works and sculpture. His design work features rhythms and patterns and has a resemblance to modern jazz and the studies of Josef Albers.
Jazz Journal was first published in 1946 by Sinclair Traill, who also had some of his photographs used on the covers. The magazine is now online but remained in print for several decades, as Britain's longest enduring jazz magazine.
