Of all the cover art out there this is the one that I find the most intriguing except for perhaps the Clerics Challenge piece by Elmore. I think it is because of the conglomeration of magic items I can identify with from other modules being present on the front cover. That an the exotic appeal the magic user. The cage I envision being the prison from the Lost Caverns, the cards being a deck of many things etc. Overall it is a well done product and it filled a niche for me as a DM.
