From 1962, DOCTOR SOLAR #1, another of my favorite Silver Age comics.
The writing is smart, and the artwork by Bob ("Fuje") Fujitani is sophisticated. Later on Solar took on a costume and I thought the comic lost something, but I always had the first issues to look at. Another big plus for me at the time was the cover by Richard Powers, one of the top paperback cover artists of the day. I collected his work then as now.
