Please help in determining authorship and assessment

[Борисъ]

Help identify authorship and make a rough estimate of pictures.
The first two pictures (the picture and its reverse side) in an album in the style of " Cubism " with the caption , author , Bernard , is dated 1932 .
Second , without a signature. (Sorry ).... Acquired in Western Ukraine. Canvas tight , white, (obviously not Soviet ), but somehow sewn into two parts ? Written by a professional, visually looks very, very much. Seen a similar style of writing in Chaim Soutine > Rama is seen not native. Cloth nailed to the frame edges are not smooth, probably was cut . Big thick strokes of paint. One can see the hand of professional master.
I would be grateful for any help .
With Vs . Boris
