A young “cowboy”, the son of a member of the Air Force Flight Test Center, Edwards Air Force Base, California, looks over the Convair built YB-60 during its visit at Edwards from the Fort Worth, Texas, plant. 1953 (U.S. Air Force photo)
The YB-60 was a long-range bomber prototype built for the Air Force. It was in unofficial competition with the B-52 Stratofortress for an Air Force contract. As the B-52 is still in service, I guess we know who won the contract.
As for who won the showdown in the photo, my money is on the kid.

Amazing shot. That kid is definitely thinking, “I think I can take it!”
What an amazingly 50′s-looking kid. Even more than the plane he evokes the era.
He definitely looks the part.
