Breaking the Code
Robert Sean Leonard from 1988.
I figured out where my Playbill for Breaking the Code, which I saw in January 1988, was. I broke open a trunk (that wasn't supposed to be locked) to get it. Scanned it (it only took about 60 tries to get these right.)
And then I tried to upload them to LiveJournal. Riiiiight. It absolutely refused to let me not crop the pictures. So, instead, here's the link to my Breaking the Code Photobucket album.
There are only 8 pages (and 1 picture of Robert Sean Leonard). This was his second Broadway appearance and the first where he originated the role.
Enjoy.
