Hey!
I found a copy of The Empire Strikes Back, OFFICIAL COLLECTORS EDITION 1980 at my deceased grandmother's home.
I have found the value to be $40.00 BUT I have what I believe could very well be the only known misprint. I have searched the internet tirelessly for 2 days and haven't even seen a comment on a misprint/flaw.
I come here in hopes of valuing this book, not to sell it!
