As told by Jack Wickham , Grandson of E.T. Wickham ...
My Dad, Harvey Wickham, son of E.T., told me this story when I was in High School. I asked him what was E.T.'s first work of art, and he said that the earliest thing he remembered was when E.T. bought a farm on Sadlersville Road in Robertson County sometime in the 1920's. E.T. lost the farm in the 1930's Depression and moved back to the old Palmyra homeplace. The story from Dad goes that the mailman did not show up everyday with the mail. E.T. accused the mailman of holding his mail and only coming to the end of the road to their farm every other day or two. E.T. said the mailman was too lazy to ride his horse the extra half mile down the road to the Wickham farm. The mailman took offense and said it wasn't true. E.T. said he thought the man was lying. Finally the mailman said "Tanner, if I never see your face again, it will be too soon." Whereupon, the mailman turned and rode off down the road.
Afterwards, in a moment of inspiration, E.T. went around the back of the house, and in a low area in the back yard that was mostly clay, E.T. poured water onto the ground, and worked up a clay puddle that was pliable but firm. Dad said that when E.T. had it in the right consistancy, he stuck his face in the mud slowly, and then pulled it out slowly. He let it dry for the afternoon, then mixed cement and poured it into the clay mold and let it set overnite. The next morning, he pulled the concrete cement out to reveal a mold of his face. He worked it some to fill in the gaps, painted it in his likeness, and then attached it to the front of the mailbox. Now the archenemy postman had to look at E.T.s "face" everyday while making his duly appointed delivery rounds. Soon afterward E.T. began sculpting concrete decorations and statues.
Who would have thought an angry exchange between E.T. and a mailman would have lead to his statues being on display at the 1982 World's Fair!
