On the cover slip of every volume of Detective Conan, there is a different picture of Aoyama being murdered in some awful way on the inner 
cover flap.  On the back cover is a portrait of one of the characters, always different.  Also, there is a different famous detective 
described on the inside of the back flap.  Just for fun, I decided to keep a list of all these different things here.
