What can I say about this work
 

32h26 I found my old job, done on cardboard, than do not understand.

On the back of cardboard punch w.koller & Co chemiker in Wien, Silberue Medaille 1845.

What can we say about this work?

To determine the equipment necessary to show an increase in the part of the picture.
Indeed, these cartoons were produced for artists by W.
KOLLER & C.
Chemiker in Wien.
(Silberne Medaille in 1845.) In the network there are a few oil paintings, Polish artist relating to 1879 -1882 years.
Perhaps, we should look for a signature.

Signed try another search . Can I find .
