Vulcan was an experiment for IPC, a title reprinting popular strips from other IPC comics with a glossy cover (mimicking American imports), printed smaller than regular UK comics to match the size of imported US comics, and with three colour strips in each issue (in some cases coloured from the original black and white printing). At least partially an attempt to take on the U.S. imports, the majority of Vulcan's strips were of "super heroic" bent. Because this was breaking new ground, IPC chose to do a limited test release of the title, and on March 1st 1975 the first, unnumbered issue was published, but only available in Scotland. After thirty issues, Vulcan's distribution was widened to the whole of the U.K. as of 27th September 1975; though the 31st issue, it was numbered as issue one. Despite this, all the stories were continued from where the Scottish edition had gotten to. The numbered, national edition of Valiant ran to #29 before cancelling and merging with Valiant, ironically the original source of many of the strips in Vulcan. There was also a Vulcan Holiday Special and a Vulcan Annual 1977...
