“The Wonderful Wizard of Oz” is a classic tale by American author Frank Baum in 1900 and it has delighted many of us for over a century.
One character in particular, the Tin Man, lacking a heart, wildly pined for one, earnestly lamenting: “If I only had a heart.”
When discovered on the road to Oz by the heroine of Baum’s story, Dorothy, the Tin Man had been severely rusted by exposure to the elements. Dorothy cleverly used oil and saved him. The Tin Man readily became Dorothy’s protector who was ever-poised with his ready axe in hand.
