The porschinger`s name is all over it,many different names,There is atleast 100 signatures in it.A few are von Stauffenbergs family.I was able to make out a few other names.My under standing was this was from a castle there.The story is : a G.I. was guarding the castle and he had 6 duffle bags of souveniers,but was only allowed to keep 1 bag.This was in it.Years later he sold his collection to a ww2 collector I know,everything but this book.Years alter he died and his wife called and said she was willing to sell it,so he bought it.That was about 30 years ago,well times are tough and now my friend needs money,so he sold his collection of stuff for $80,000 but kept the book.Well it`s been a few more years and his bills are piling up so he sold it to me.He never spent anytime researching it,he just knew it was worth keeping.Ill post another pic of a page or 2 shortly.
