1939 WORLDS FAIR Poster

It is a framed poster of the1939 WORLDS FAIR created by Nembhard Culin. It measures 12x18 inches
It is in excellent condition
How can I tell if it is an original or a copy
Thanks

 

One way is to compare size. In what sizes were the original posters produced?

I found a version that looks-wise SOLD in 2015 on
https://www.invaluable.com/auction-...-1990-in-1939-the-new-york-w-180-c-6e44717bbb, same artist.....20” x 13-3/4”...., and you say yours is 12” X 18”...similar, but is yours cropped a bit or not....

I don’t have an account there to check the price, I think you have to join.....check it out!!

 

@steve richards, I have a question for you.....at the BOTTOM of that yellowish curve around the sphere - is the printed signature of “CULIN” fairly sharp??? I think it should be, ASSUMING the SOLD INVALUABLE poster is authentic!! I also JUST did color comparisons...SOOO different.......and the copyright isn’t showing on yours (could be behind the matte).

 

looks like maybe a poster.......of a poster.......
