I can get dimensions of it in a couple days. What size should it be for it to be original? It’s pretty big. approx 25″ x 38″

I bought them from a sketchy guy on craigslist. So I have no idea what to think if these are real or not. Do you have any info on the original WW1 signs? Did they use metal, was it double sided, anything about the ‘post office blue’ frame. (I was told these signs were made to be in front post offices (but could be false info).

The person I bought it from showed me this site: http://darrellgambler.com/shop/uncle-sam-recruitment-sign/

And he had a convincing story saying there is no info on this and if the ww2 sign is selling for that high, the ww1 sign should be at least that high. The sign looks very real and the screen printing looks real, (not a decal). So I really don’t know what to think. Just trying to get a professional opinion on this thing!

Thank you!!
