Lot of 100+ Vintage 1977 Topps Star Wars Portrait Cards - Luke Skywalker, Vader

This is something that I picked up from a garage sale! I dont know much about it but its a pretty unique item! All the cards vary in condition and are all some type of portrait shot or just shots of the main characters! I dont know which cards are which and have already packaged them so please only purchase if you are happy to receive the cards shown in the photos :-) Conditions may vary from damaged to great; Thanks!
