Out of print now, but Star Wars: Chronicles by Deborah Fine. Big, cool slip-case cover, nice full-color pictures and descriptions of everything from the original trilogy, including those cantina aliens that may have been onscreen for a split second.

My other go-to is The Complete Far Side (a 2- volume set, 2003). I think the Far Side has been collected a few time over, but this has a gorgeous slip-cover with full-color "paintings" and two nicely bound volumes.
