Hi, I recently got this from an estate. What do you guys think? It seems like the real deal, It's on a 8x10 I'm planing on getting this authenticated to display in my collection. Hoping you guys can give me an opinion on it. I hope it is as I love Marilyn <3 Been collecting her vintage stuff for years. Also any good recommendations on places for authenticity? Thanks P.S. Love the Blog :)
