The Enemy Below
The Enemy Below ( 1957 ). I believe this may be an alternative printing for the first release of The Enemy Below in Australia in January, 1958. There may also be a full colour version of this duotone daybill design. Has anyone ever sighted an image of a full colour daybill ? 0

I'm off to watch this now, that poster put me in the mood for it...
Love to see the Australian one sheet poster you referred to.
Here you go.
Interesting that for The Wayward Bus and The Three Faces Of Eve the green duotone daybills were printed by W.E. Smith and the colour daybills by Robert Burton but with The Enemy Below the green duotone daybill was printed by Robert Burton.
A question unanswered is were there green duotone one sheets printed for any of these three titles? I don't believe so myself.
