A response by "Comicbookrehab" to my "Masked Mallard" post brought to my attention the fact that The Masked Top Hat (Italian: Tuba Mascherata), who I mistakenly thought made his first appearance in Boom! HERO SQUAD #8, had actually appeared in several stories before that. Two, to be precise. Unsurprisingly, the actual debut came in an Italian story, "Paperinik e il mistero di Tuba Mascherata" ("The Duck Avenger and the Mystery of The Masked Top Hat"), in TOPOLINO #1632 (March 8, 1987). Yep, TMTH actually appeared 2 1/2 years before The Masked Mallard. Subsequent European reprintings of the origin story seemed to have some difficulty in accepting the whole idea of Scrooge as a masked hero, given that they couldn't keep to a strict template as to how the character was supposed to look.
a followup story for TIO PATINHAS #328 (October 1992). This tale doesn't seem to have caused the same stir as the original; it was only subsequently reprinted in Italy, in an oversized paperback entitled MEGA 2000. Scrooge must have disposed of most of the original costume in the interim, as he is obliged to wear his usual broadcloth coat this time around. At least the ancient garment accessorizes easily.
