Is there any interest in these cans?

A very nice and rare can there. Don Francisco was an early California racer in the 1950's and very well known. Search "Don Francisco racing" or Wikepedia for much more info. That can would be popular for early Drag Racing or Gas & Oil memorabilia as well.

Thank You for the information
