While Bust Portrait of Actor Kataoka Ichizō I is an ichimai-e [一枚絵] single-sheet print, it is also the right half of a diptych. Its partner to the left is Sadamasu's portrait of actor Arashi Tokusaburō III [嵐徳三郎] (1812-1863) as the play's hero, Iwanaga Jirōkichi [岩川次郎吉]. The image is identically formatted with the exception of the actor's head angle, which mirrors that of Kataoka Ichizō's.
