I don't know if you have looked this up before. But here is the aerial photo from 1996 of 491 S. Holmes - click the photo where you want to zoom in at.

Thanks. My monitor is very old and the screen is darker than what I was used to before, so I can barely make out things on terraserver anymore and don't have my old account there.
Without street labels, I can't tell much of anything, but I'll try to take a look later on. Appreciate it.
