famous Marilyn Monroe poster, is this one a repro?

first picture is for reference, it is from a recent auction. These were sold in the early 50s in the back of magazines such as Popular Science they are about 60" tall so they get a lot of attention when they come up for auction. But the recent one that came up at auction it has more wording on the bottom left it says "..write: Life Size, Dept X, Redstone NH." that is picture 2. Picture 3 is from a worthpoint listing and you can see it has less wording just "...Marilyn Monroe". So I was wondering if these are both authentic or is one or both a reproduction?

 

Are these 60" tall?

Alternate wording on the following link, all on the right side, and then none shown on the other.

On one worthpoint the size given is, 62 1/4 inches long by 21.5 inches wide.

Another auction says, 63 1/2 by 27 1/2 inches, overall.

 

It may have been printed over several years in the 1950s? That may account for the paper sizes. Is the paper yellowed or toned?

 

Hello Roaring: Yes these were both about 62". The top one was from the recent auction it went $380 which makes sense if the retail price (ebay or similar) goes about 700. (going from memory). Ive seen them go over $500 at auction pre covid so they always do very well.

I passed on the recent one but as I was looking at them I was struck that the wording was different. I figured the one with the PO Box was the repro now I am more confused as to why there are at least three different versions.

I was not at the auction in person so I could not use a loop or anything else to check it closely.

 

well like I said I was not there in person and these are the only images I saved. its an interesting issue.
