Simple design before the advent of CAD/CAM

This trishaw was abandoned in the front yard of a home. It might not fetch any useful value now, but notice the piece of labourious art work done, comprising two prawns and a crab, located just above the back rest of the seat. This is obviously a very simple hand design done before the advent of Computer-Aided Design (CAD) and Computer-Aided Manufacture (CAM) techniques.
