What should I do with this vintage ticket?

Going thru my older books the other day, my wife found a very old book I have had for years, and found inside a ticket to the 1928 Golden Jubilee Concert and Ball of the Widows and Orphans Put on by the San Francisco Police Department. The ticket is is great condition, and appears to be collectable, but I have no idea what to do with it.
No item like it appears on Ebay, or in a Google search. How do I value such an item? I am not even sure if the Widows and Orphans still have an organization. I am not against donating it somewhere, but I don’t want to be taken advantage of, and have some bozo profit off of this.
Ideas?
