And now, some proof of the existence of the white variant Deathmate Epilogue:
CGC, the most widely accepted grading authority in the industry, graded this book with a green "qualified" label. The green label is used when there is writing on the comic, parts are missing (such as coupons that have been cut out), or collectible production errors are present. Here they remarked on the green label that the book was "Manufactured without silver foil on the cover".
UPDATE: I hate talking about eBay but I thought it would be interesting to some to know that this bad boy ended up selling for a cool $100 plus shipping.
