I found this classic 1930's or 40's era Chicago streetcar photograph, at a Facebook page entitld "Forgotten Chicago". (A really nice photo site.)

 

I liked this photograph so much, that I also shared it on my own

Facebook site "North Side Chicago."

 

This classic double ended Chicago Surface Lines electric streetcar,

was photographed at the northeast corner of West Armitage and

North California Avenue, on the north side of Chicago.
