Several people have told me that they prefer the original title font that was used on the covers of the earlier printings of the Swords & Wizardry Core Rules. The reason for ditching the original font was because Blackletter fonts aren't good for off-the-shelf sales if the book goes into distribution. Since, if Swords & Wizardry goes into real distribution, it would be the Complete Rules, that issue doesn't exist any more.
So, for those who really, really want that original title font on the cover, I have put up a retro version of the book with the original title font. It's the same interior as the regular 4th printing -- the only difference is the title font. It is only in hardcover, and has the same price as the regular hardcover.
