I do not know if these were originally with or without signatures, canvas do not look like it was tightened but I am not sure, I can only guess.. I asked my parents but they do not know much more, only that the second one was cut off when re-framed, not much of professional work, but they are certain there was a signature before re-framing.. other two paintings nobody knows.. Grandfather passed years ago and I am not sure if he knows anything about it too, as far as I know he collects these oil paintings and most of them were gifts from his friends.
