Castle San Marcos National Monument Vintage Linen Postcard Unposted

I am posting items from a Family estate. I am not a postcard expert, so please ask any questions prior to purchase. They are fragrance and smoke-free. This particular card is approximately 3.5.” X 5.5” Linen/textured Genuine Curteich Chicago “C.T. Art Colortone” See photos for exact conditions. I see no issues. Willing to consider offers for bundle.
