Rare and important large Oeil de Boeuf (bullseye) window from an important 1905 Hospital designed by architect's Hurd & Sutton of Newark, NJ.  One photo is from the 1930s and the other is just before the building was demolished, to show how the windows were used.

Hand crafted copper with a stunning verdigris patina only obtained with age.  

Would make a great mirror or can be used in new construction.  

Condition:  PLEASE NOTE:  We did not get photos of the back side of this window, the ones in the listing are from another window, but it gives you a good idea of how it is constructed. Copper would need some work to be stabilized on the back side.  The lower back sides of each is slightly bent and missing the flat pieces that would have been along the back side.  I added two pieces of wood (easily removed) to allow the window to stand up without pressure applied to the lower edge.  

A great deal of time was taken to get these down from the building.  These are exceptionally rare and one of a kind.  Can be used for many different things, both interior and exterior.

Please take a look at the other architectural  items I have from this same building.
