Pierre Bonnard Au Théâtre Lithograph

Trying to figure what year of edition is the print. Original or reproduction? The lower left of the sheet is signed with "Au Théâtre". To me it looks like graphite but may be wrong. The litho paper size is approx. 12 1/4" x 9 1/2". No publisher or printer text.
Thanks

 

Without inspection I wouldn't confirm, however it appears to be the well-known reduced size facsimile issued in 1952 by the Atelier Mourlot.

If so, it's still collectible but at more modest price.

 

Thanks for the reply.
Do you know if the 1952 restrike was done on a black back paper and if there should be any printed text? How about the pencil signed title?
Thanks

 

The 1952 prints were not restrikes. They were reduced size facsimiles [reproductions].

The paper was not black. In fact, there was printed text on the back.

It looks like possibly, in your case, a sheet of black paper was adhered to the back, covering the text...possibly with the aim of camouflaging its identity as a repro/facsimile. This is speculation. Yours looks like the 1952 printing. Can't imagine what else it would be. However, as stated, I cannot tell for sure without hands on inspection.

The title in pencil has no significance.

 

Thanks. I will inspect the paper to see if the black was laid over the back.
