Can you help?

This is probably a weird request, but I hope to find someone who can help me.

I am currently working on a game about the American revolution (1776)
I am looking for pictures and a plan showing the Graff House in Phillidelphia.
Apparently Thommas Jefferson rented two rooms on the upper floor and I am trying to make the game as realistic as possible.
I have tried to search the net, but I can’t really find what I’m looking for…
Please help…
Thanks in advance…
Cheers

I’ll bet money there’s a Historical Society in Philadelphia. They may not be online at all, but if you phone the public library in Philly and ask, I’m sure they can give you a phone number to call.

Thanks for your help…
I found them (with a little help) and wrote them an e-mail…
Got a very kind response…
