The Steven Lomazow Collection of American Periodicals
One of the largest periodical collection of all time. The Steven Lomazow Collection consists of almost 30 thousand issues dating back to the early 1700's. A finer collection of periodical artwork you can't find any where else.
I have a copy that looks the same as this, and at bottom inside of the front cover says:
“Copyright 1965-S.R.I. […] Win a free copy of Volume Three – send us acceptable gags and jokes!” My similar copy of volume two (MORE FROM SEX TO SEXTY) has the same message.
