As reported on the Acaeum by Metamorphosis Sigma, WOTC has released updated covers for the 1E re-releases, which now say Advanced D&D (rather than just D&D) and correct the spelling of "Players" and "Masters" to remove apostrophes, as per the originals. I stitched the three thumbnails together so we could see them side by side.
They are better than I expected. WOTC found a nice way to update the covers yet use part of the old art. I'd prefer less squiggles/curlicues but it's ok. The color scheme (brown background with yellow and red) reminds me of the World of Greyhawk boxset cover.
I have 2+ copies of the originals of each of these manuals, so I'll let others have first chance at these new ones. I'll only buy them to send a message of support for reprints if they don't sell out immediately.
