The first four years of Doc Savage pulps had some of the best covers. News of the Man of Bronze had made the rounds and everyone wanted to see what this new crimebuster was all about. Here are the covers from 1933 to 1936. As far as I understand such things, this material is all in the public domain. If not, let me know and I'll make like Houdini. In the meantime, enjoy!
In 1934 you could shovel driveways on one side of the street and sidewalks on the other and maybe make enough to buy a Doc Savage--a deal at twice the price!
In the 1930s a dime could buy ten loaves of bread and a motorcar to drive them home. There was also some great stuff in the pulp section of the newsstands.
Here's what the Man of Bronze was up to between 1937 and 1939. There was a lot of competition if you were lucky enough to scrounge up ten cents and the Doc Savage cover artists were more than up to the job!
