RogueHunter: Well thank you for trying to research my "favorite" work of art.
The subject matter in the lifesize work I saw so often was exactly the same as what is depicted by the photo you posted.
The two MAJOR differences are the art work I referred to was in charcoal (black and white) and Abraham Lincoln was looking directly at the art admirer with eyes fully open and directed forward.
I will do some looking myself - I have forgotten the name of the charcoal painting I admire but recall that the work was "commissioned" by and for the Employees of Washington Mutual Bank?

P.S.: Found YOUR colored Lincoln painting and it is 34" by 17" whereas the Washington Mutual owned piece was lifesize tall and lifesize width - and it was signed by Norman Rockwell - perhaps its "commissioned" work status kept it from being catlogued here and there?
