We are always buying comic collections recently we found this cool article from May 20, 1973 from the Los Angeles Herald Examiner in one of them. Headline states " Initial Superman Book Brings $1,800" . The book was purchased by Mitch Mehdy. At the time that was a huge sum for a comic, though that book now sells in the millions!
If the book is as nice as it looks in the photo it is high grade!
Also in the collection a copy of the 1974 Overstreet Comic Book Price Guide.
