I suspect that these letters are from the predigital era.
As a substitute you might try Cooper Black Swash Italic, designed by Oswald Bruce Cooper. A digital version is available as Umbriago NF http://www.myfonts.com/fonts/nicksfonts/umbriago-nf/ You might need to compress it to fit the bottom line.
BTW there used to be a digital version of Cooper Black Swash Italic by Ian Lynam published by Wordshape at Myfonts, but it is no longer available there. You can get it at http://www.youworkforthem.com/font/T3177/cooper-black-swash-italic

Another option is Bookmania Black Italic http://www.myfonts.com/fonts/marksimonson/bookmania/black-italic/glyphs.... which lacks the rounded "friendly" letters of your shirt or Cooper, but as you can see has a huge variety of swash letters.
