The 1937 $1 is black with a green tint. It shows King George VI on the face
and an agriculture allegory of a seated female on the back.
The "Gordon-Tower" variation of narrow panel or wide panel can be
identified by the spacing of the King's portrait edge and the notes border.
On the above "Coyne-Towers" note, you can see the "wide panel" image.
Notice that the edge of the King's portrait almost touches the border.
This creates a wider area for the signatures to appear. On the "narrow
panel" notes, there is about three times more space between the edge
of the portrait and the border of the note.
