Chuck Dixon and artist Guido Guidi continue their special look at the Industrial Age reign of the TRANSFORMERS. In Hearts of Steel part 3, 19th Century scientist Tobia Muldoon has evidence of the existence of the DECEPTICONS and their plans for the domination of Earth. But will anyone other than Mark Twain believe his fantastic story? Or will the ASROTRAIN roll into New York City and change history forever? This issue features two covers from Guidi, one a concept art cover.
