These are both in very good condition with tight binding. Thuvia has a slight lean though. There's a price in pencil on the first page, but otherwise, there are no markings and the pages are nice and clean.
The covers are clean, but Llana has a bumped top front corner.
The dust jackets have great color and of course extremely cool imagery. The are both price clipped in two places. The Frazetta one has just a little wear at the extremities. The Corben one also has wear at the extremities with a little more creasing.
Please see pictures.
