The seventh position in my grid is directly to the left of grid #6, continuing to move in a clockwise direction on the original grid of 11 paintings.
The design on this grid entry stands on its own, but is also part of the whole. However, if this grid entry was a jigsaw-puzzle part of the bigger grid, I venture to say that one would have to put all the rest of the pieces together first before realizing where #7 fit.
