Decker's Dark Dames

I watched The Two Mrs. Carrolls (1947) recently and loved these paintings from it:

The first Mrs. Carroll as The Angel Of Death

The second Mrs. Carroll (Barbara Stanwyck)

I found out they were painted by John Decker.
So was this portrait of Joan Bennett from Scarlett Street (1945):

[It's the masterpiece of his 12 paintings in the film.]

And the lady on the calendar in Brute Force (1947):

This is the original:

She was a cadaver he painted at a morgue!
Decker died that same year. More info here.
