HEAD OF A NEGRO PRINT REPRODUCED BY TRITON PRESS INC NYC

I own a print of "The Head of a Negro". Painted by Peter Paul Rubens. I am trying to find out what year the artist painted it . I can't seem to find out. The print I have was reproduced by Triton Press, but does not give me a date that the original was painted or what date the print was produced.

Thanking you in advance,
Ron Brown
