I recently finished the SA Captain America Omnibus by Lee and Kirby. Stories were pretty cheesey, but I loved the Kirby artwork. The bulk of this book was from Cap's run in Tales of Suspense, which he shared with Iron Man, so most of the book is composed of 10-page stories, which makes for a quick read.
Blind-buy for me, but I felt my collection needed some Kirby and Lee's Captain America.
