Hello, I am hoping someone can help provide any information. Please find the attached the photos of a promo poster advertising the Making of Michael Jackson's Thriller. I can't seem to find this particular poster anywhere and I want some advice on its rarity and potential estimated value. I noticed there was quite a few differences on my poster compared to others more common found online, for instance the layout, format and the fact it says March release which is too early considering it was released in December 1983.
Many thanks in advance for any advice!
