Help identifying an artist and/or painting

I bought this for relatively little and the person had no information on it. It seems to be painted on canvas or printed on canvas? Perhaps it is a reproduction of a famous painting? the artist initials appear to be AB or OB?? I can post pictures of all....the frame was not original- the seller put it on thinking it went well with the piece. Thanks! I can't even tell you what medium was used or if it is really old or fairly new
