Jack Dempsey Signed Menu

I found this Jack Dempsey signed menu in a box of photos from my mother's estate. I'm curious about its value. It is inscribed to my Great Aunt Hulda. She and her husband were quite the travelers and hob-knobbed with all sorts of celebrities. I have no idea where they may have connected with Mr. Dempsey.

It is from the Broadway Bar and Cocktail Lounge, New York. The signature is dated 1940.
