The news came courtesy of writer Gordon Dymowski on Twitter.
I'm proud to say that I solved that mystery in a matter of minutes!
The anthology in question is in comic book form and while it is still in the planning stages, each story should run somewhere between 4-8 pages. The original Black Bat's stories were first published between 1939 and 1951 and therefore the character is no stranger to Nazis. Gordon Dymowski is likewise familiar with the Black Bat, having contributed the story "The Magnificent Anderson" to Airship 27's third volume of Black Bat Mystery.
It appears that Erik Franklin will be handling art duties. Erik also contributed a story to volume three of Black Bat Mystery entitled The Dark Magician and has seen his work included in anthologies for Sherlock Holmes and The Purple Scar as well, among others. I don't know of any published work as an artist, however.
It seems that interest among creators is such that there may already be enough material for a second issue. They do want to get the first one out there quickly though so it should not be long until we are all...
