...to tell if it is the correct book? how can i be sure that the book im buying is infact a first printing from 1988. i cannot simply go by the color of the lettering on the cover (first print is green) because there have been reprints in later years (which also are green). also on some of the graded comics the title is followed by #nn or something similer. i am fairly new to buying comics and dont want to take the sellers word on weather the comic is the correct one or not. also is there any type of price guide book or website that can help me identify comics? thanks!
