Trade Edition First Printing Identifier: Lists to "The Mystery of Monster Mountain" on the back cover.

Other Trade Edition First Printing Traits:
- Matte cover finish
- Blue graveyard endpapers

Notes:
1.) A later printing of the Trade Edition was manufactured with the glossy cover finish. This printing lists to "The Mystery of the Dead Man's Riddle" on the back cover and it has the blue graveyard endpapers.
2.) Interestingly, one can also find matte cover Trade Editions listing to "The Mystery of the Dead Man's Riddle" and having the blue graveyard eps.  This should be considered an earlier printing than books with the glossy covers.


- As shown to the left, later printings of the GLB Edition used Robert Adragna's cover art.
