Only Canadian price on the cover. However these printings are not considered Canadian since they were printed, stored and mailed from the USA. There are three printings with the same HRN number. One printed by Gilberton, one by Island Publications and one by the Nassau Bulletin. The Nassau Bulletin is the one with the Canadian price.
This issue is a variant of Classic Comics (Gilberton, 1941 series) #19 - Huckleberry Finn
