I was referred to this forum by Steve Cyrkin. A form of this posting appeared on his forum this past August.
So I'm going through a box of old books at home that belonged to my Aunt Rosemary who turned 100 years of age this past July (she tells me she's finally downsizing.). In it I find a copy of THE CHALLENGE TO LIBERTY, 1st edition, 1934 by Herbert Hoover in pristine condition w/ an undamaged, clean and tight paper jacket. I open the cover and read, "To my friend, Rosemary M.., with best wishes, Herbert Hoover".
The next book I pick up is a first edition (limited to 50,000 copies according to the dust jacket) of NEW FRONTIERS by Henry Wallace signed inside the front cover. The paper dust jacket is in very good condition w/ extremely little tattering around the edge of the spine.
I have checked on line, and to my untrained eye, both signatures looks authentic (That plus, it's doubtful Aunt Rosemary had any nefarious intentions when she gave me the box in the first place). What do I do about this (if anything)?
I can post photographs if that would be useful.
