Have a look at the latest listings of daybills on HA eg ....
The Day the Earth Stood Still (20th Century Fox, 1951). Australian Post-War Daybill (13" X 30").
It seems that instead of describing them as original, looks like some will now be either PRE WAR or POST WAR but the word "original" doesn't get a mention.
I guess that is the result of the unresolved issues re Wizard of Oz, Robin Hood, Sea Hawk, etc etc
