O Morcego Negro

The image below was among the results of a search for "Black Bat" on flickr.com, of all places. Hoping to perhaps come upon someone sharing pulp-related art, I was instead rewarded with an early 1950s cover to a Brazilian publication spotlighting the Black Bat. Clicking on the image will take you to the page on which it was found.

The poster, going only by Komic-Kazi, has an album specific to that publication. All images appear to have been added during the second half of 2022.

I've tracked down the following information from Komic-Kazi's Facebook page.

Komic Kazi International has been involved in archiving and researching international comics and art on a scale not seen before.

Founded by Mr. Ott and assisted by his sons, Skye, Stefan, and Shawn this family owned and run operation has been collecting vintage comic books and comic art for over 50 years.

Their total collection includes over 125,000+ rare international issues and thousands of pieces of original published comic book art from across the globe. Both the rarity and high state of condition of their holdings cannot be overstated.

I know nothing about X-9 Magazine specifically but Komic-Kazi's displays helps a great deal.

At a glance, the ones featuring the Black Bat seem to range in publication date from 1942 to 1958. Many of the covers are near-replicas of the Black Book Detective ones and the titles, translated from the Portuguese, would also suggest that most stories are reprints of the original material.

Neither of those two criteria apply to the cover displayed above, however, unless "Simpson's Curse" is an original story under a different name. Either one of the great many German stories was translated into Portuguese instead or, much like the German novels, publisher O Globo also put out a few original tales of their own. 

The most recent update to the album was Christmas day. Hopefully Komic-Kazi has more to share. This has been a fun find.
