This is the only example of an apology (more of an explantion) on the front wrapper of a magazine that I've come across. It is self explanatory.
The editor of Boston Magazine in November 1783 went a little further inside his second issue of his magazine, basically asking his readers for a "do-over".
It apparantly worked. The magazine lasted until 1786 and published some great engravings.
By the way, if anyone out there in cyberspace has or knows of a January 1785 issue of Boston Magazine for sale, I need one to complete my run. Thanks!
