CONOR McCreedy returned to his alma mater, Hilton College, last week to share with the pupils some of the secrets of his meteoric rise in the international arts world. McCreedy moved to New York City, enrolled in the prestigious Pratt Institute and set about making his mark in the art world. His first pitch was in Manhattan’s Union Square where he would sell his paintings to tourists to pay the bills. It was there that a German couple spotted him and paid $2 500 for one of his works. “It was the first proper sale of my life,” he said.
