There's nothing as amazing as seeing what happens when a caterpillar reaches its full size - shedding its skin and changing into a pupa before finally emerging as a delicate butterfly !   These stages depicted beautifully on pages 10-11 of "Butterflies and Moths" (Golden Books/ Western Publishing Co, 1993)  Original artwork, painted in oil on  paper, 15" x 20.5" and signed - a two-page spread that will look lovely framed.   NOTE: purchase 2 or more interior illustrations from this book and shipping is free (I will refund your shipping costs after purchase)
