It's not really better, per se, but it looks a bit more like a photograph now - I'm afraid there is no way that it could be gotten any better than this, given the extreme poor quality of the original, but I blurred it to remove [some of] the JPEG artefacts, which makes it look more like a [blurry] photo and less blocky, and I adjusted the contrast and converted to greyscale.  I don't know what you had hoped for, but I'm afraid this is all you can get at this point, if you don't have the original.

By the way, the description of it says it's the "Burma Cub Scouting logo" in the Fair use rationale, which can't be right and doesn't anywhere say what we're actually looking at beyond the arses of a lot of men in uniform.
