1856 Walker & Hickling’s Block, Ottawa, Illinois.
William Dunckleburg was recorded in one advertisement that ran from August 16 to October 18, 1856 in The Ottawa Free Trader (Ottawa, Illinois). Something New Again: Wm. Dunckleburg, The unrivalled Ambrotypist, has the pleasure of announcing to the citizens of Ottawa and vicinity, That he has taken rooms in Walker & Hickling’s Block, on the south side of the square, second floor, where he is prepared to take Ambrotypes by an entirely new process that has just come to light—Ambrotypes taken on glass. By this process pictures have a depth of tone that cannot be got by the common Ambrotype process, and yet possess all the light and shades.
I will remain in this place but a short time, during which all who wish a perfect likeness will do well to improve this opportunity. These pictures can be excelled by none. Ambrotypes put up in good cases for from one to twenty-five dollars.
Please call and examine specimens. Wm. Dunckleburg & Co.
William Dunckleburg is not recorded as being active in Ottawa, Illinois.
