Tarzan's Three Challenges was released in 1963 and the orignal daybill movie poster is farily rare. Experienced collectors would be aware that the original would need to carry a "For General Exhibition" censor logo. When seen together it is fairly obvious that the daybill on the right is a re release. The reissue daybill carries the NRC censor details which confirms that it was printed after 1971.
The reissue daybill turns up from time to time on ebay and is occasionally misreprented as being original release.
