This print represents cycles and balance; both of which you have toiled to understand. The eagle represents wisdom: that is you, add only 1 day.
Notice the four people in each corner, 2 males and 2 females. Also note how the black and white of the image seems to jump forward while the colours seem to recede in the background. This is an innovative use of colour. It might be expected that colour would jump to the eye first but Reg Davidson's use of sharp lines in black and white forms a bold contrast which thrusts itself into the forefront of the image.
