Blind people enjoy pornography too. That's what you'll learn when you pick up a copy of Playboy in braille. Although, if you don't know how to read braille, you won't know the difference between an ad and a description of something naughty.
The best part is that Playboy in Braille can be found in the Library of Congress. I suppose it's all part of an open access to information sort of thing. This particular copy was a vintage find (November 1995 Volume XLII - No. 11.) listed on eBay until they removed it citing that it needed to be listed in a section for mature audiences.
