Who Was This Guy Back In '38?

A month prior to the issue of Weird Tales we saw yesterday, the March 1938 issue sported this cover -

I don't know about you, but i thought that was a fairly daring cover for the '30s. When i first encountered one of M. Brundage's covers it was quite a surprise.  Not only was the work lovely, it was luridly so, with imagery i would not have guessed would be on a magazine cover back in the early '30s, as these three were -

Seriously. I'd be tempted to put these in the adult content back room if they weren't off the rack magazine covers from over 80 years ago. Who was this Monsieur Brundage fellow?
I wanted to know more, and certainly wanted to find more of his artwork.

Oh, i was so confused...

(as we'll see this weekend)

covers by Brundage for Weird Tales June & Sept. (1933), Jan. (1934), and March (1938)
