Four companies took advantage of the situation by publishing comics in Canada, sometimes using imported scripts. Anglo-American Publishing of Toronto and Maple Leaf Publishing in Vancouver started publishing in March 1941. Later, two other Toronto-based publishers joined in: Hillborough Studios that August, and Bell Features (originally Commercial Signs of Canada) in September. For the most part, the comics published had colour covers, but the interiors were printed in black ink on white paper, although there was a handful of comics with colour interiors.
