I recently acquired the movie poster "James Dean - Rebel Without A Cause". Passed on to us by a family member who was a serious collector of movie posters, Circus (PT Barnum, Bailey, Ringling), Toys, Baseball, Political Memorabilia...etc.
Based on the level of his interest in authentic collectibles I believe this poster is authentic - but - not having documentation I'm not 100%. How would i go about making sure it is authentic? Unfortunately, he has passed on so I'm not able to ask him! Any help is welcomed.
