Legends Only Tell

I legit gawked at this bust for a minute straight. I even took a picture of the plaque describing him, just in case I forgot.
If you didn't know, this is the very famous bust of Alexander the Great at the British Museum. He was awesome.
I completely forgot who that is in the background. It might be another bust of Alexander, or one of his Companions. Hephaestion maybe? Meh, idk. I just really like this picture.
