Laramie Texas cabin outlet original signed painting of cabin by Helen Cartwright "North of Laramie" 1978

Original painting I believe to be acrylic, but might be oil on canvas board. This sweet painting gives the real feeling of a cozy ranch home under a outlet cold blanket of winter sky. Painting is 14" x 11" in a painted wood frame. Signed, and annotated on back.
See picture that shows a stray mark on top.
Signed by artist.
