I have these two very nice autographs of Sgt. Alvin C. York. They are on a linen type art paper, the paper is white. They were in an envelope that was addressed by him and had his return name and address on it. They have been certified by ACE,LLC. I think they are some of the best I've seen. Wondering what some of you thought. I would like to sell them for much less than I think they are worth.
