As new in clamshell case. Limited to ONLY 500 COPIES in numbered/signed sets. I do not know how many were made available to collectors in the UK but it is obviously VERY SCARCE INDEED. This truly exceptional new set is the fifth title in the ERB Limited Edition Collection. Leather bound. And it is signed by the artists (Thomas Grindberg/Douglas Klauba/Ian McCaig), and contributors (Robert B. Zeuschner)and as if that was not enough the book itself has a final revised and corrected text. It has a new forward by Michael Moorcock who was unable to sign this edition because of health reasons. It includes 20 fabulous tipped-in plates by Schoonover, Frazetta, Whelan, Grindberg and others, and it includes new paintings specially made for this edition. A Manuscript Portfolio for Edgar Rice Burroughs's UNDER THE MOONS OF MARS is also included, containing replica manuscript pages, notes, editor letters, the Munsey check to ERB for UMM, first publication pulp cover and pages. A replica of the pen used by ERB, a 2" Deja Thoris Medallion, numbered to match the book. All inside the custom case AND THIS COPY IS STILL SEALED so that means it is a pristine UNREAD new copy. A truly epic collectible. PLEASE NOTE: THIS IS HEAVY. It will need EXTRA SHIPPING depending on destination. LEATHER BOUND - New - SEALED.
