It is pretty striking alright. My guess is it is a Brown & Bigelow image from around 1935-1937; looks like the same photo session as these:
An Adam Hats Louis would be awesome, but I have never seen one. No African American boxers at all in the H815 run, though there is a photo of Harry Cook in an oversized 2nd generation Adam Hat premium that I've seen (not sure these are even official Adam Hats pieces). But no Louis or Armstrong, or any other AA fighter of the era.
