I just got a nice card from Dr. N-R-Gee (see photo, Richie Rich Cash #1, September 1974).
"Saw your post on my young cousin, Dr. Domino! Just so you know, Dom is alive and well; we vacationed together last month at Easter Island. He says he feels rested and ready to go back into action in the DCU. He says, 'If there's a new Starman, he shall rue the day he crossed the path of ... DR. DOMINO!' Oh, Dom, you lovable nut, you!
P.S. Send my regards to Black Mask and the rest of the False Face Gang!"
