Description

1778-1943 Americans Will Always Fight For Liberty Poster Bernard Perlin WWII.
I have found this item at garage sale, unsure of authenticity. To my first glance I see an old rundown item, which makes me think it’s been around for awhile, making it a real piece or an early reprint. I can also see the fold lines of where the poster would’ve been folded like an authentic one. I also thought the measurements were interesting/strange, but then again I have no idea what any of it actually means.
Would love to know the basis behind a real or fake print if anyone was willing to share their knowledge! Please contact me with any thoughts or interest. Thanks so much.
