Here is another interesting (and rather fameous) Morphy game, which is yet not archived under articles/amazing games in chess.com.

"King's gambit game" from 1857, where Morphy played the black pieces against John William Schulten.

I have added comments to the moves where they are getting interesting ... and consistent with Morphy's typical intricate and aggressive attack style ...

 If you want more P.C. Morphy ... At the site: http://chessgames.com/perl/chessplayer?pid=16002 , more than 400 of Morphy's games are stored; you can select them by opening strategies, white/plack pieces, etc.

Also chess.com has archived approximately 10 of his games under articles/amazing games. Enjoy !
