Where can I find a photo of mathematician and economist Charles Wiggins Cobb?

Hello,
I need to find a photo of the mathematician and economist Charles Wiggins Cobb (most known for his Cobb-Douglas production function). I have managed to gather little data on him but would really need to obtain a picture whether it is in electronic format, or if anybody has a book containing his photo laying around and can scan it (the photo) for me.
Any help would be grately appreciated. Google didn't really come through for me this time.

You might try to contact the Math Department or Library at Amherst College.
