You're welcome. I've attached a photo marked in the lower right "Copyright by John H. Tarbell" from the collections of the Library of Congress. The original copyright has expired and because it's in the Library of Congress there are no new copyright restrictions on its use, in case you want to link it to your site.
When I wrote back thanking Mr Emlen he replied:
Attached was this terriffic photo taken by John. (click on it for a larger version)
