I took the  scanned negative and vectorized it, and pseudo colored some of the elements of this image, that would be the drapes, masks gowns and equipment in pale shades of blues and greys. I particularly like the nurse in the upper right, i only call her a nurse instead of a doctor or resident because these were the ages in which women just did not go to medical school.  Times have thankfully changed.  While this was state of the art 70 years ago, how primitive.
