Still concerning reprints of American books during the WECA period, I guess you have to mention the Gilberton Classics Comics in 1946 and you must also bring up the fact that certain American comics that were deemed to have some 'educational' value such as the Parents' Magazine Publishing comics (True Comics, True Aviation Picture Stories, etc.) were allowed through. Even here though, there is a collectible difference in some. The tile of the American 'True Comics' was changed to 'True Picture Magazine' in Canada and had a Canadian context story inserted in it. Take a look at the difference between the American True Comics 17 and the Canadian.
