Modern putters are not the only golf clubs that use color and creativity to sell. That whole world was developed decades earlier.  For example these Stewart Maiden Grand Slam Model 20 Wood Set w/ Ivory. are spiffy indeed!  Driver, brassy, and spoon have ivory back weights and what appears to be ivory inlay in the face. 42” driver. Original steel shafts with four channels grooved out down their entire length. Beautifully refinished. Gorgeous and actually very few such sets remain.
