It looks to me like this is a reproduction of an ad that may have run back in ‘64 when “Meet The Beatles” was initially released. From the size of it, it looks like it may have run as a 2 page, double spread ad in trade magazines like Billboard, Cashbox, and Record Retailer.
This is a reproduction of that historic ad. My understanding is the red “Meet The Beatles” was black in the original. There may be some other differences, but I do not know for certain what they may, or may not, be. In any event, this is what it is, and what you see is what you get.
Poster measures approximately 20x14, is in mint condition, and will be shipped flat, as it has a stiff backing.
