Unframed abstract oil painting on paper laid down on board

Titled, Non Objective Abstraction

Signed on back and dated 10/11/64, signed and dated on front '65

I am unable to clearly makes out the name...possibly Jack Baker, Basher, Bashen ???

Measures 15" x 11"

Overall good vintage condition, having minor wear to one corner and a crack in the paint at the top

Very nicely painted
