Jehlinger refused to write a book or do any publicity for himself, even refusing to have his picture taken. I have only found one photo of him. The article below is something I searched for but I had given up on finding one. But this past week brought me to a chance find of someone mentioning that there was an article. There are no links to it. It is written in the style of the day, and so the language is dated. It was written in 1945.
If you would like to see my first post on Jehlinger, it has direct quotes from numerous movie star autobiographies, as well as quotes from Jehlinger on acting.
