I am not a professional grader, this is my opinion as a comic collector and fan. 

I have never seen anything quite like this. It appears to a be a guide of fun facts for the United States, from the Golden Age of Comics! I don't have much experience with golden age books. It looks to be in good shape for its ages, just the staple rust and the detached centerfold. Maybe a 2.5 - 3.0? 

Please use your judgement grade, I can send more pics if needed! 

Book will ship bagged and boarded, bubble wrapped in a cardboard mailer. I will combine shipping on multiple orders, thanks for looking!
