"Jack-knife" Pic?

[MacPelto]

I have seen somewhere, a picture of Elmer Keith shooting a rifle in the "jackknife" position. It's a kind of sitting position where you cradle the fore end in the crook of your support arm.

Does anyone out there have a copy of this picture that they'd be willing to share, please? A scan or something would be great, but even if you could remind me where I saw this pic so that I could go look it up again, I'd appreciate that, too.


Thanks in advance

Mac
