Just picked up this poster and two things that I noticed as being off from what I normally deal with:
No fold marks that I can discern
The paper is glossy as opposed to the newspaper-like material of other period posters.
Now I normally collect War Bonds posters so this may be just different being a recruitment poster but I just wanted to check. The age seems on par and there's a note on the back dating it to 1954 so I doubt they would have reproduced it so soon. The measurement is 42"x28" so that is correct at least.
Welcome your thoughts, thanks!
