Expressionist Winter Scene in Grodno signed J. Lipchitz

Winter scene in Grodno, Belarus or Lithuania dated 1948.  This wonderful painting is signed J. Lipchitz and annotated Grodno 1948.  We have been unable to determine the author.  The well known cubist artist and sculptor Jacques Lipchitz came from this region, however this painting does not look like any of his work or signatures that we have seen.
