Great Debate Books
Henry Regnery Co., generally known in the publishing world as a conservative outpost, created this series in 1962 to highlight conservative works and thinkers. Books in the series were uniform in size, at 6" x 9", perfect-bound, and sold at $2 each. The first five titles were released in April 1962, but the series was not long for this world, petering out after a couple titles in 1963 and one in 1964.
