The Man of Bronze and The Land of Terror by Lester Dent.
The first two Doc Savage novels.
The first Doc Savage novel I read was The Land of Terror back in either 1971 or 1972. It was a Bantam reprint that I picked up at store in Panama City just outside the Balboa Gate. Since then, I have read over 160 of the original 181 Doc Savage novels, as well as several by Philip Jose Farmer (licensed or otherwise) and Will Murray. IMNSHO, Doc Savage was the greatest of the Pulp Era Heros.
