I think this must be a later printing of the first issue. The back cover lists up to issue 360 and the cover price is 75 cents instead of 1.25 pesetas. The back cover ad on issue 101, which the info card says is from 1947, offers a list of early titles for 75 cents. This suggests that the publisher did a Classics Illustrated thing and kept old titles in print, changing the price and the back cover list from time to time. Unfortunately the majority of our early issues are missing the back cover so it's hard to tell for sure.
