Philadelphia as Seen from Cooper's Ferry

[grindieloe]

I know this is way OT, but regardless, you guys never disappoint me 
with your vast amount of knowledge about EVERY topic!  

In any case, my boyfriend is a HUGE fan of the book Arundel.  If 
anyone if familiar with it, you know that they continue to mention 
this picture called "PHILADELPHIA AS SEEN FROM COOPER'S FERRY."  I 
have looked everywhere for a picture of Philadelphia as Seen from 
Cooper's Ferry!!! I even went to www.cityscapes.com.  They had tons 
of photographs of Philadelphia, but I have no idea if any of them 
are seen from Cooper's Ferry.  I even wrote to them and they said 
that they really don't know either and that I'd have to ask someone 
who lived in the Philadelphia area.  

So, my questions to you guys are: 1)Would anyone be able to tell me 
if any of those pictures on cityscapes.com is Philadelphia as Seen 
from Cooper's Ferry?; and 2) Does anyone know of any really great 
photo/picture/art sites that may have what I am looking for?

Anything you could tell me would be great, as he has looked for this 
for YEARS and has not been able to find it.  It certainly would make 
for a great surprise birthday present.

Thanks...
Andrea :)
