Design: Grey Gull label designs were of a very high standard of commercial art, showing a good balance between delicate decoration and bold typography (compare similarities with other Grey Gull products, Lyratone, Supertone). Though quite legible on a white background, gold print vibrates on blue (and red; compare with another Grey Gull product, Supreme).
History: As previous. Radiex employed several different designs during its existence, from 1923 to 1930. Alternate scan (below) courtesy of collector Ken Hagelthorn of the U.S.A.
