    Howard Simpson, Bob Layton, and Gonzalo Mayo Harbinger #15 Cover and Complete 21-Page Story Original Art Group of 21 (Valiant, 1993). This turned out to be an important issue as it introduced the characters Livewire and Stronghold, who would go on to be major players in the Secret Weapons series. This cover was by Howard Simpson and inked by Bob Layton. The inside pages are by the team of Simpson and Mayo. The book featured the usual Harbinger cast of Sting, Flamingo, Zeppelin, Kris, many of the Harbinger Foundation Eggbreakers, and Toyo Harada. The cover and pages are produced in ink over graphite on Bristol board with an image area of (on average) 10" x 15". The cover is 11" x 17", matted to 18.5" x 24". The two page spread of pages 4-5 is on a single sheet of Bristol board, matted to 29" x 23" with an image area of 22.5" x 17". Every single story page is signed by Gonzalo Mayo. The group comes with a copy of the printed comic issue that is also signed on the cover by Gonzalo Mayo. The pages have minor handling issues, and all text and captions were produced in Valiant's unique method that leaves paste-up "placeholders" on the page for placement. These have discolored, as is usual for Valiant pages, and many are popping off, which is also very usual for Valiant pages of this era. This does expose the original art beneath, however it sometimes leaves glue residue on the page as well. Some entire panels were stats produced in this method and some have come loose, exposing the original art below. Overall, these are in Excellent condition.
