This is an intricately painted seedpot by Robert Kasero, Sr..  It is very thin walled and painted with an “op-art” style of spiral lightning and rain design. The triangles are the lightning extending down from the rim to the base.  The “lines” are the rain.  It is dynamic in the flow of the tightly painted designs.  Note how the base of the seedpot is also indented keeping in the style of historic Laguna pottery.  It is signed on the bottom.
