Yes - I did see one on eBay a while ago that was similar to the one we have but with MOW looking straight rather than his head turned. As I recall, that photo had a full background.
The Cook print that we have appears to be a "stylized" conformation shot. The cropping was done by hand, probably with an exacto type blade. Pretty high tech back then!
I actually colorized a scan I made of that print. If you want, e-mail me at YoTam@socal.rr.com and I can send you what I have.
