'My father didn't frame his work, he painted the entire canvas to the wall, as it gave the sense of continuance and the work was a perspective he provided, but there is always more to the story, more off frame. He invited the audience to build and complete their story from where he left them space to grow.'

Wonderfully expressed. And completely in line with how you describe him.
I can only imagine the grief.
Wish you and yours strength mate.
