Forum:KB:Admiral Trench Missing Concept Art

I was watching the 2015 Star Wars Celebration Bad Batch Panel and one of the slides of concept illustrations were of Admiral Trench (my personal favorite antagonist) About 15 and half minutes in I see this illustration where I can barely make out the words "Admiral Taranch [...] B" which I screenshotted and cropped. I went to look for the illustrations in the concept gallery of the Bad Batch section on Star Wars' official page but found no result. Come to think of it, I could never find any released art of Trench himself, the closest thing I could find was his flagship, "The Invincble" Does anyone know where to find such concept illustrations of Trench/Taranch?
