I stumbled across this great video - and wanted to share!
Elmer Leterman was one of Gordon Alexander's inspirations (you can search for where he's mentioned in previous posts)...
This video is called the Elmer Leterman story. It's about the technique Elmer Leterman used to set a sales record in New York - in the middle of the Great Depression.
It would probably still work today... (During the pandemic, you could do it with Zoom or Skype...)
The video is just 3½ minutes long...
