My dad also liked to paint and sketch on natural materials (like leaves, shells), so most of his art was ephemeral and has perished.
But last year I met Dr. Byregowda, a publisher who took great pains to collect and publish many of my dad's illustrations ("Kamatara Kuncha Prapancha", 2012), and now wants to bring out a new book.
So I asked my wife to dig up a family heirloom -- my mother's saree that my father painted circa 1980. The saree is all worn-out, but the white acrylic featuring the "beauty with the mirror" is intact. Many such sarees got lost during a robbery in Calcutta in 1979.
