Wednesday Advertising Day.
The Captain Tootsie ads by C.C. Beck and Pete Costanza appeared both in Sunday and daily newspaper ads. The Sunday ads were often reformatted and used in comic books. This makes Captain Tootsie the only comic book cahracter who appeared in books of (almost?) all publishers. As far as I know no one has ever attempted to create a complete overview of all ads in the newspapers and how where and when they were used in the comics. It must be a huge task, but also one that the internet seems built for. All someone has to do is st up a ebsite, start by uploading all of the ads I have shown over the years and ask comic book and newspaper fans to contribute new scans to the timeline.
