I have a Don Henley signed book "Heaven is Under Our Feet - A Book For Walden's Wood" - The autograph looks good to me,it is signed and dated,though it is not psa verified,but my question is - would his Autograph be more valuable if I had it cut & slabbed,instead of keeping it in the book? Iam asking for knowledgable opinions on this subject - Thank You in Advance!!
