Having seen this tree quite a few times over the last few years at Brussel's, the photo is authentic. If anything, it's far more impressive in person. I cannot find a pruning scar or graft union ANYWHERE on it, but the bark looks like black pine...all the way up. It's an impressive old tree, but really needs to grow wider so the trunk doesn't look quite so fat. I think the primary branch to the left died back and they managed to save a few shoots that will serve to rebuild it over (a LONG) time...
