Here is a wonderful dated 1929 etching titled "A Passing Landmark. Pacific St. Cable. San Francisco" by Blanding Sloan. 

The sheet size measures 6.5" x 8.5". It is pencil signed and titled lower margin. It has an even toning throughout the image, though it could be bleached. Full margins and a nice impression. Pictures should tell the story. 

Buyer pays $10.00 for shipping within the US. Thank you.
