Hidden damage

From the bottom third of the mural one can see where the added layers of paint are, how to recognize them and the extent of surface that they cover.  The recoated areas are clearly visible in normal light: the background has been completely and repeatedly painted over.  Within the leaves and forms there are punctual touch-ups that “jump-out” because of their colors.
