The Magica/Gladstone pic is from one of the Polish "Gigant" books. The original appears to be called "Amelia & Gastone e la fortuna di troppo", was written by Antonella Pandini, drawn by Alessandro Gottardo, and was originally published in 1998. Haven't read the story myself, but just fyi, cause by lorde and heavens above, you made me fall for that pairing (please give us more !).
