Featured Some thing Abstract found again

And this one I have never found any similar painting on the net so any idea about Artist en when made and where ? Thanks

 

Someone named Wim who was active in 1966.
The only one I can think of is Wim Jonkman, but as far as I know he signs with 'Jonk'. He does have a very varied oeuvre.

 

Looks incomplete to me with all the sketching but maybe that is what the artist intended.

 

I also thought that was all just part of it.

 

Me also think because off the name and date on it that this is a finished painting as is . Wim Jonkman I had al look but nothing yet found by him in this style .

 

Artist Terry Winters. *shrugs*

 

Funny you came up with Winters. I thought it looked like Winter also and tried to see if Max de Winter could be right but I gave up.

Any info on the back?

 

Also had a look at Terry winters but I don't think there's any link with him . On the back nothing . But in my eyes I see a cross on the left site and a face behind the cross ? So any religious meaning in the painting maybe ?
