When was the painting deep in the winter woods painted by grif teller?

I have a framed print of Deep in the Winter Woods . The original painting was almost certainly used by the Osborne Company for their calendar line and the print has the title printed at the bottom. I am Grif's daughter and remember many such prints from my childhood. I can't remember precisely when this one was painted but it was most likely in the 1940's, give or take a few years.
