This is a rare 1976 classic, Marvel Preview Presents #4, Star-Lord.  This book has some mileage and imperfections, but it still holds some value for sure.  You will see a noticeable bend on the bottom left corner of the back cover.  You will also notice in the pics some heavier than normal staining and spotting.   But this book still has plenty of positives.  Book is very structurally sound, with all pages intact.  Book is free of any tears.   Besides the above mentioned bend on the back cover the remaining portions of the front and back covers (especially if cleaned) are very solid.   This raw, natural 48 year old book can still regain some former glory with some TLC.  With all of this said, I am NOT a professional grader so I highly encourage you to study the pics and make your own judgements.   I always aim to be transparent, so please feel free to ask for additional pics, or ask additional questions.  Thanks for your interest.
