After he was forced to discontinue publication of The Penny Magazine in association with the SDUK in 1845, Charles Knight apparently could not resist an attempt to continue with the publication, even in a diminished form. I only discovered the existence of Knight's Penny Magazine by accident. It existed for only one year, in an octavo page format, rather than the original quarto format of the original series. Knight published two volumes of Knight's Penny Magazine through the year 1846. The one interesting marketing ploy that Knight appears to have added are the two semi-nude "muses" supporting two thinkers and writers on the title pages of the two volumes published. Knight also published advertisements inside the printed wrappers of the original issues of the magazine. As far as I knew in December 2020, this was Knight's first and last experiment with selling ads inside his publications.
