I hadn't noticed the photographer credits, Bunker Hill. Interesting, too, is the fact that four of the photos are dated June, 1935, and attributed to Lomax. Two others (including the one posted above) are dated November, 1935, some five months later, and attributed to Carl Van Vechten. Brown may have been in New York at the time of these later photos -- perhaps due to his recordings for Lomax? Just a thought. For the curious, I'm posting one of the earlier photos that Lomax took during his field recording of Brown.
