It could be a Classic Jungle, if several other characteristics are present:
1) This is the most obvious. Classic Jungles have an extremely yellow coloration and a very busy pattern.
2) Upper half of the eye is gold/yellow, as if the gold stripe along its brow continues through the eye itself.
3) A distinct faded spot on top of the head. This should begin showing up after a few sheds, so pay attention. It will get lighter AND more distinct with each shed.
I think I got all of the important ones. You should check out the Sutherlands' site (ballpython.com), click on the "morphs" link. He has a very good description of the traits of a Classic Jungle, and few good pics of faded spot on the head and the black flecks on the upper lip.
