S . ▁mag az ines . ▁ ▁Canadian ▁ed itions ▁from ▁ 1 9 4 2 ▁up ▁to ▁January ▁ 1 9 4 8 ▁were ▁not ▁identical ▁to ▁the ▁U . S . ▁ed itions , ▁but ▁they ▁match ▁closely ▁enough ▁that ▁the ▁original s ▁are ▁easily ▁identified . ▁ ▁From ▁the ▁May ▁ 1 9 4 2 ▁to ▁January ▁ 1 9 4 5 ▁issues , ▁they ▁correspond ▁to ▁the ▁U . S . ▁ed itions ▁two ▁issues ▁earlier , ▁that ▁is , ▁from ▁January ▁ 1 9 4 2 ▁to ▁September ▁ 1 9 4 4 . ▁ ▁There ▁was ▁no ▁Canadian ▁issue ▁corresponding ▁to ▁the ▁November ▁ 1 9 4 4 ▁U . S . ▁issue , ▁so ▁from ▁that ▁point ▁the ▁Canadian ▁issues ▁were ▁only ▁one ▁behind ▁the ▁U . S . ▁ones : ▁the ▁issues ▁from ▁March ▁ 1 9 4 5 ▁to ▁January ▁ 1 9 4 8 ▁correspond ▁to ▁the ▁U . S . ▁issues ▁from ▁January ▁ 1 9 4 5 ▁to ▁November ▁ 1 9 4 7 . ▁ ▁There ▁was ▁no ▁Canadian ▁issue ▁of ▁the ▁January ▁ 1 9 4 8 ▁U . S . ▁issue , ▁and ▁from ▁the ▁next ▁issue , ▁March ▁ 1 9 4 8 , ▁till ▁the ▁end ▁of ▁the ▁Canadian ▁run ▁in ▁November ▁ 1 9 5 1 , ▁the ▁issues ▁were ▁identical ▁to ▁the ▁U . S . ▁versions . ▁ ▁There ▁were ▁numerous ▁differences ▁between ▁the ▁Canadian ▁issues ▁from ▁May ▁ 1 9 4 2
