I thought I'd already posted this cover but I guess I changed my mind when I couldn't find a copy of the pencils. Fortunately, the long forgotten preliminary sketch showed up on eBay this week and it's tight enough to get the job done. It's not my auction but you can see it here, for a few more hours at least. The seller very kindly shared a larger scan of the rough with me so please reward him with some ridiculously high bids.
